Meanwhile, In Afghanistan…

The latest quarterly report from the Special Inspector General for Afghanistan Reconstruction (SIGAR) has been released. America’s military involvement in Afghanistan passed its 15th anniversary in October.

The data presented in the SIGAR report show some disturbing trends. Through the first eight months of 2016, Afghan national defense and security forces suffered approximately 15,000 casualties, including 5,523 killed. This from a reported force of 169,229 army and air force personnel (minus civilians) and 148,480 national police, for a total of 317,709. The casualty rate undoubtedly contributed to the net loss of 2,199 personnel from the previous quarter.

sigur-02Afghan forces suffered 5,500 killed-in-action and 14,000+ wounded in 2015. They have already incurred that many combat deaths so far in 2016, though the number of wounded is significantly lower than in 2015. The approach of winter will slow combat operations, so the overall number of casualties for the year may not exceed the 2015 total.

The rough killed-to-wounded ratio of 3 to 1 for Afghan forces for 2016 is lower than in 2015, and does not compare favorably to rates of 9 to 1 and 13 to 1 for U.S. Army and Marine forces in combat from 2001-2012. This likely reflects a variety of factors, including rudimentary medical care and forces operating in exposed locations. It also suggests that even though the U.S. has launched over 700 air strikes, already more than the 500 carried out in all of 2015, there is still insufficient fire support for Afghan troops in contact

Insurgents are also fighting for control of more of the countryside than in 2015. The Afghan government has lost 2.2% of its territory so far this year. It controls or influences 258 of 407 total districts (63.4%), while insurgents control or influence 33 (8.1%),  and 116 are “contested” (28.5%).

sigur-03The overall level of violence presents a mixed picture. Security incidents between 20 May 20 and 15 August 2016 represent a 4.7% increase over the same period last year, but a 3.6% decrease from the same period in 2014.

sigur-01The next U.S. president will face some difficult policy choices going forward. There are 9,800 U.S. troops slated to remain the country through the end of 2016, as part of an international training and counterterrorism force of 13,000. While the Afghan government resumed secret peace talks with the Taliban insurgents, a political resolution does not appear imminent. There appear to be no appealing strategic options or obvious ways forward for ending involvement in the longest of America’s ongoing wars against violent extremism.

They are on Schedule

Well, they are on schedule: iraqi-forces-attempt-first-push-mosul

Two weeks ago Peshmerga Brigadier General Sidwan Barzani (nephew of the president and telecom millionaire) said that there would be a two-week advance and a six-week mop up. So far, they appear to be on schedule. I do note that a number of the talking heads on U.S. TV seemed to discount this prediction.

Anyhow, they have entered the eastern suburbs of Mosul today (Monday). We shall see if this is over in six weeks.

Syria and Iraq After The Islamic State

As Iraqi forces close in on the northern city of Mosul, the commander of U.S Joint Task Force-INHERENT RESOLVE, Army Lieutenant General Stephen Townsend, indicated on Wednesday that preparations are being accelerated for isolating Raqaa, Syria, the capital of the Islamic State. The attack could begin within two weeks, The Daily Beast’s Nancy Youssef reported on Thursday. Townsend stated that the timing is being influenced by evidence of Daesh planning for terrorist attacks on unidentified targets in the West.

According to Townsend, the projected offensive against Raqaa will include elements of the Syrian Kurd YPG militia. “The only force that is capable on any near term timeline are the Syrian Democratic Forces, of which the YPG are a significant portion,” Townsend said. “We’ll move soon to isolate Raqqa with the forces that are ready to go.”

Although YPG has not stated whether it is willing to participate in an attack on Raqaa, Turkey has expressed its opposition to involving the Syrian Kurds, which it says will “endanger the future of Syria.” Turkey is actively fighting a domestic Kurdish insurgency and has launched military strikes on Syrian and Iraqi Kurdish forces.

The U.S.’s willingness to back the Syrian Kurdish forces over Turkey’s objections are a clear harbinger of the challenges facing the region even after Mosul and Raqaa are liberated from Daesh control. Liberating Raqaa will not end the civil war in Syria and will not spell the end of Daesh. Daesh forces still control wide swaths of territory in Syria. Will the U.S. remain committed to fighting Daesh in Syria after Raqaa falls?

U.S. and Iraqi military leaders have predicted that Daesh will continue to wage an insurgency in Iraq as a potent guerilla force. After Mosul falls, the Iraqi government faces the prospect of a grinding, open-ended counterinsurgency effort fueled by unresolved sectarian divisions. Is the U.S. prepared to maintain its support for open-ended Iraqi counterinsurgency operations after Mosul is recaptured?

Interwoven into these questions are bigger, regional questions. Will the Syrian and Iraqi Kurds be allowed political autonomy in those parts of Syria and Iraq liberated from Daesh control? Will the Free Syrian Forces become the de-facto government over the parts of Syria not under Assad’s control? What is Iraqi Kurdistan’s future in Iraq? While the liberation of Mosul and Raqaa will constitute manifest defeats for Daesh, these forthcoming victories do not appear that they will be decisive in resolving the ongoing local and regional political conflicts.

Wounded-To-Killed Ratios

Some wounded-to-killed ratios drawn from my upcoming book War by Numbers: Understanding Conventional Combat. I have an entire chapter on the subject in my book (Chapter Fifteen: Casualties). This first chart is from Trevor Dupuy’s Attrition:

table01

A table I created to compare U.S. Army and U.S. Marine Corps ratios:

table02

A tabled I created looking at the U.S. units the I Corps area of Vietnam. This is after the Tet offensive, and these units are operating side-by-side and listed from north to south. The 1st Bde, 5th ID was up at the DMZ while the 23rd (Americal) Division was in the southern part of I Corps:

table03

And finally the ratios from Iraq and Afghanistan. Note these are higher ratios compared to what is reported in the previous post for the Iraqi Army and the Peshmerga.

table04

This is why the Iraq Army and Peshmerga wounded-to-kill ratio in the previous post caught my attention.

Body Counts

Have some estimate of losses from the operations around Mosul. See: us-general-says-800-900-fighters-killed-mosul

This operations have been going on since Monday, October 17, so I am guessing they cover a 10 day or so period.

A few factoids:

  1. Up to 900 Islamic State fighters killed (source: Gen. Joseph Votel, who heads the U.S. Central Command).
  2. There are between 3,500 – 5,000 ISIL fighters in Mosul (I assume we have not really engaged them yet).
  3. Up to another 2,000 ISIL fighters in the broader area (I assume this is who they have been fighting).
  4. As of late Tuesday Iraq Army had lost 57 killed and 255 or so wounded.
  5. For the Kurdish Peshmerga the numbers are 30 killed and 70- 100 wounded.

Let me do a little back-of-the-envelope calculations here:

  1. 900 ISIL killed versus 87 allied killed = 10.3-to-1 exchange ratio. This seems high.
  2. Wounded-to-killed ratio Iraq Army = 4.47 wounded per killed (this seems low)
  3. Wounded-to-killed ratio Peshmerga = 3.33 wounded per killed (this seems low)
  4. Wounded-to-killed ratio ISIL…unknown, but with 900 killed then are there 1,800 are 2,700 wounded…or are there no wounded?
  5. If there are wounded, then if total ISIL casualties (killed, wounded and missing) are 2,700 – 3,600 and there are 2,000 ISIL fighters in the broader area…..then…….

The body count seems high. What appeared to be more relevant in Vietnam was the number of rifles and other personal weapons taken after the battle. The assumption was that most dead warriors left a weapon on the battlefield. Often the weapon count was less than half the estimated number of killed.

It appears that the estimate of 900 ISIL killed may be high and the Iraq Army and Peshmerga reports of wounded are low. This seems to happen a lot.

Odd Nobel Awards

nobel_prize

It is really hard to find a more distinguished award than the Nobel awards, created by Alfed Nobel, the Swedish “merchant of death” that invented dynamite and owned Bofors. But there have been a few prizes awarded that are a little odd to say the least. Earlier this month they awarded the Nobel peace prize to Juan Manuel Santos, for negotiating a peace agreement to end the 52 year war between the government of Colombia and the rebel group Fuerza Armadas Revolucionarias de Colombia (FARC). But five days before the announcement of the prize, the peace deal was rejected by a referendum of Colombian voters. So, peace prize awarded, but no peace.

Just in case the Colombian War has not been on your horizon, not only is it the longest running hot conflict in the world, but it has resulted in the deaths of over 200,000 people. This makes it the second bloodiest war ever in the Western Hemisphere, behind the U.S. Civil War (1861-65) and ahead of the Chaco War (1932-1935).

The war has always operated at a fairly low level. The bloodiest year for the counterinsurgency forces was in 2002 with 1,207 deaths and an estimated 1,817 insurgent deaths. By 2005 these figures had dropped to 143 and 63 respectively. The peak U.S. involvement was in 2002 with 224 advisors. These figures are drawn from our Dupuy Insurgency Spread Sheets (DISS). We never assembled a total figure of deaths from the war so cannot confirm the often used figure of over 200,000 killed, but starting in 1988, the number of homicides in Colombia exceed 20,000 a year, and they were less than 10,000 a year only five years earlier. The war peaked in 2002 and is much, much quieter now.

There have been other strange prizes awarded over the years, like President Obama getting awarded one in 2009, when all he had done to date was get elected nine months earlier. There was a prize awarded in 1973 to Henry Kissinger and Le Duc Tho for the Paris agreement that brought a ceasefire in the Vietnam War. Le Duc Tho refused to accept the award. The war continued for another two years after the prize, culminating with North Vietnam overrunning South Vietnam. Certainly it was peace at that point, but hardly in the spirit of the prize.

There is one Nobel prize awarded recently that was not odd, this was the literature prize for Bob Dylan. About time! There is no question that Bob Dylan was the single most influential lyricist (and therefore poet) in world in the last 50 years. Before Bob Dylan, song lyrics were basically “she loves you, yea, yea, yea.” After Dylan, there wasn’t a whole lot of subjects not being addressed. Dylan came from a rich American folk and blues tradition very much developed by Woody Guthrie, Leadbelly and Pete Seeger. He embraced it, enhanced it, and left an indelible mark on popular music. Just as Homer originally recited his poetic narratives to music, many modern poets are singers and songwriters. This prize just recognizes that obvious, but sometimes overlooked point. People don’t read or write a lot of poetry these days, but they do listen to a lot of music and lyrics. These lyrics are often bad poetry, but not all of them. Some published authors and poets have become song writers (Leonard Cohen and Rod McKuen come to mind, for example). They did not cease to be poets when they became song writers. Even the name of this blog is drawn from a “popular song,” just to drive home the point. Modern poetry often includes a backbeat, be it NWA or Bob Dylan.

Last verse:

Yes, my guard stood hard when abstract threats

Too noble to neglect

Deceived me into thinking

I had something to protect

Good and bad, I define these terms

Quite clear, no doubt, somehow

Ah, but I was so much older then

I’m younger than that now

Disease

The AIDS epidemic has always held my attention because it is a modern disease that was recently spread. Serves as a warning as to how difficult it is to respond to a new disease or a new variant of a disease. One can certainly imagine a number of biological war scenarios, or something like a new Spanish Flu epidemic like happened 1918-1920. Disease and plague have certainly played their part in history.

Anyhow, spotted an article that indicates that the AIDS virus came into the United States from the Caribbean to New York in the 1970s. This makes a certain amount of sense. As the virus does take time before it shows symptoms, it was clearly around for a while before the doctors first spotted it in California in 1981.

There is a more detailed article in Nature that I have not pulled up.

Tank Loss Rates in Combat: Then and Now

wwii-tank-battlefieldAs the U.S. Army and the national security community seek a sense of what potential conflicts in the near future might be like, they see the distinct potential for large tank battles. Will technological advances change the character of armored warfare? Perhaps, but it seems more likely that the next big tank battles – if they occur – will likely resemble those from the past.

One aspect of future battle of great interest to military planners is probably going to tank loss rates in combat. In a previous post, I looked at the analysis done by Trevor Dupuy on the relationship between tank and personnel losses in the U.S. experience during World War II. Today, I will take a look at his analysis of historical tank loss rates.

In general, Dupuy identified that a proportional relationship exists between personnel casualty rates in combat and losses in tanks, guns, trucks, and other equipment. (His combat attrition verities are discussed here.) Looking at World War II division and corps-level combat engagement data in 1943-1944 between U.S., British and German forces in the west, and German and Soviet forces in the east, Dupuy found similar patterns in tank loss rates.

attrition-fig-58

In combat between two division/corps-sized, armor-heavy forces, Dupuy found that the tank loss rates were likely to be between five to seven times the personnel casualty rate for the winning side, and seven to 10 for the losing side. Additionally, defending units suffered lower loss rates than attackers; if an attacking force suffered a tank losses seven times the personnel rate, the defending forces tank losses would be around five times.

Dupuy also discovered the ratio of tank to personnel losses appeared to be a function of the proportion of tanks to infantry in a combat force. Units with fewer than six tanks per 1,000 troops could be considered armor supporting, while those with a density of more than six tanks per 1,000 troops were armor-heavy. Armor supporting units suffered lower tank casualty rates than armor heavy units.

attrition-fig-59

Dupuy looked at tank loss rates in the 1973 Arab-Israeli War and found that they were consistent with World War II experience.

What does this tell us about possible tank losses in future combat? That is a very good question. One guess that is reasonably certain is that future tank battles will probably not involve forces of World War II division or corps size. The opposing forces will be brigade combat teams, or more likely, battalion-sized elements.

Dupuy did not have as much data on tank combat at this level, and what he did have indicated a great deal more variability in loss rates. Examples of this can be found in the tables below.

attrition-fig-53attrition-fig-54

These data points showed some consistency, with a mean of 6.96 and a standard deviation of 6.10, which is comparable to that for division/corps loss rates. Personnel casualty rates are higher and much more variable than those at the division level, however. Dupuy stated that more research was necessary to establish a higher degree of confidence and relevance of the apparent battalion tank loss ratio. So one potentially fruitful area of research with regard to near future combat could very well be a renewed focus on historical experience.
