The recent discussions about removing the Red Crosses on white backgrounds from the Army’s MEDEVAC helicopters created quite an uproar from Army leadership. They based their arguments against doing so mostly on a misunderstanding the terms of the Geneva Convention. They also disregarded an opinion issued in October 2008 by the Army’s Judge Advocate General – International and Operational Law Division to the Surgeon General of the Army/Commanding General of the Army Medical Department (AMEDD) which said that a proposal to remove the Red Crosses and arm MEDEVAC helicopters is not a violation of the law of war or the Geneva Convention.
Another argument put forth is about how the Red Cross symbol itself is a morale booster for troops. They argue that arming the helicopters would require the removal of the very symbols that lift spirits out in the field. It seems more likely that morale is boosted not by a paint scheme, but by the anticipated arrival of a medical evacuation aircraft. It is a matter of conditioning – troops would cheer Barney the dinosaur if it was painted on the nose of armed MEDEVAC helicopters.
It’s Not Easy Being Green
This got me thinking about the color of the Army’s unarmed MEDEVAC helicopters in Afghanistan. Afghanistan is mostly devoid of forests, and the terrain is more likely to be described as being beige or grey rather than green except along rivers. Yet, MEDEVAC helicopters – like other Army helicopters – sport “Aircraft Green” paint that was selected in the Cold War when the expected battlefield would be the Fulda Gap in Germany or the jungles of Southeast Asia. That dark green shade is out of place in Helmand Province and elsewhere in Afghanistan as much as it was also out of place in Iraq. However, the Army’s fixed wing aircraft have adopted the light blue-grey color long favored by the US Air Force, US Navy and US Marine Corps for its helicopters and fixed wing aircraft:

Sometime between 2006 and summer of 2010 the Army Aviation Applied Technology Directorate conducted research to determine the best colors to reduce detectability of helicopters across desert and vegetative terrain and against sky backgrounds. The tests assessed visibility at distances of 1km and 3km from a computer modeled ground observer.
Color samples were obtained from desert terrain in AZ and CA, and vegetative background colors were gathered from Monterey and Carmel Valley in CA.
The results included three recommended monotone paint choices – optimized tan (FS30372) for desert environments, optimized green for vegetated environments and a mixed color (FS34201) paint for mixed desert and vegetated terrain.
This is the mixed color solution applied to a test CH-47F airframe:
The tests showed that increasing the camouflage color more to the blue-grey end of the scale did not reduce the ability of the program to identify the helicopter against the sky. The sky has so many different lighting conditions that the program was always able to discern the helicopter. The problem was the underside of the helicopter will almost always appear black from a distance in the sky regardless of the color it is painted because it is in the shadow of the aircraft. As a result, the Army elected to downplay the need to camouflage its helicopters against a sky background, and to emphasize camouflaging them against terrestrial backgrounds.
During the Cold War the Air Force trained its pilots in T-34 and T-38 trainers. In order to minimize the risk of mid-air collisions the Air Force painted its trainers white with red or orange tails and wing tips because that scheme that yielded high visibility for the aircraft. After additional research the Air Force determined that the color scheme that yielded the highest visibility was black accented with white:
• Dark background? Check.
• White contrasting sections? Check.
• Red markings for enhanced visibility? Check.
Wait! Isn’t that the standard paint on MEDEVAC helicopters in Afghanistan? Ah, yea as a matter of fact it is!
Well, seriously. How important is visibility in an age of shoulder fired missiles? Does it really matter that the Army paint scheme maximizes visual perceptibility for ground observers?
According to a just released Department of Defense study of U.S. aircraft damage in Afghanistan the following weapons were responsible:
(1) Includes all hand-carried rifles such as the AK-47.
(2) Includes all larger caliber, typically mounted, weapons such as the 12.7 mm DSHk and PKM. Also includes the 14.5 mm ZPU family of weapons.
(3) Man-Portable Air Defense System
In Afghanistan, as in insurgencies in general, the bad guys do not have an air force. This relieves the concern of a visual look-down, shoot-down scenario where a terrain matching paint scheme would provide some protection. Unless a major power is sponsoring the insurgents, they also tend not to have shoulder mounted anti-aircraft missiles or other systems that use heat seeking, laser or radar targeting systems. This has been the case in Iraq and Afghanistan. The types of hostile fire that downed American helicopters are visually sighted small arms (e.g. AK47s), heavy machine guns, and rocket propelled grenades. So choosing a paint color that minimizes the ability of an enemy to accurately find, track and target an airborne unarmed MEDEVAC helicopter sounds like a pretty good idea.
Aircraft High Lights
One thing that the Army paint tests did get right – the undersides of aircraft tend to be perceived as being black because of the angle of the sun relative to the aircraft. This is not a new problem. As a matter of fact it was addressed by the US Navy during WWII when it discovered that the success of its anti-submarine patrols against surfaced submarines was less than expected. In the days before widespread installation of radar German U-Boat look-outs were able to visually spot the black image of the approaching aircraft 12-15 miles away which gave the Captain plenty of time to dive the boat and make targeting it much harder.
In a surge of ingenuity the idea of counter-illumination was tested under Project Yehudi. Strong spotlights were placed on the leading edges of the wings and around the engine cowling of Navy Avenger dive bombers. By adjusting the brightness of the lights to match the ambient light level behind the aircraft the distance at which the aircraft could be discerned dropped from 12-15 miles to about 2 miles. This made it possible for the plane to get close enough to a submarine to launch a torpedo or drop a bomb before the submarine had time to dive.
Similar tests also were conducted successfully on Army Air Corps bombers with the lights arrayed beneath the wings and fuselage of the aircraft because of their higher altitude flights.
While the Project Yehudi tests were successful, the spread of radar to submarines and ground anti-aircraft batteries made the lighting solution less useful and the idea was dropped. It was resurrected under Project Compass Ghost during the Vietnam War when the massive F4 Phantom flown by the Air Force, Navy and Marines proved to be exceptionally easy to spot visually due to its size and smoke trail. The lights reduced the visual acquisition distance by 30% but proved inadequate to the task. An outcome that was adopted was the blue grey color now used extensively on aircraft across the US military…except the Army’s helicopter fleet.
Currently, research is being done with electroluminescent panels on drone aircraft that has demonstrated once again that visual target acquisition is significantly impaired when Yehudi/counter-illumination lights are deployed.
So What Now?
This seems to be a perfect scenario for the Army to adapt either:
• The color that the Army Aviation Applied Technology Directorate determined at least two years ago to be optimal for helicopters in Afghanistan to use, or
• The well-established helicopter color scheme used by the USAF, USN, and USMC for their helicopter forces.
At a minimum it seems that unarmed, unarmored aircraft such as MEDEVAC Blackhawks should benefit from anything that reduces their susceptibility to visually aimed ground fire.
The cost would be minimal and would require no modifications to the airframe or change orders for helicopters in procurement other than a change in the paint color to be applied.
Would the new color scheme provide reduced visibility in all conditions? Certainly not, but either new color scheme does better than the solid OD green currently used.
The Army doesn’t send combat medics out with ground units dressed in fluorescent yellow uniforms…does it?
(Note to self: check if combat medic uniforms are designed for highest possibility visibility.)

Is DOD really as stupid as it appears to be?
This commment is unpublished.· 6 years agoHeywood all I can say is yes, I think the DOD is really being that stupid. They have been a day late and a dollar short on every innovation that has come about from these latest two wars. Sad, but true.
This commment is unpublished.· 6 years agoIf I could, I would make the people who make decisions at the DoD get in one of the helicopters and take off only to see the medieval chopper be shot up by tablian then they will Chang their minds really quick and make the much needed common-sense policy change also I shook my head with rage this morning when the DoD decided to give up night time raids into the dagger heart of the tablian. Outrageous !!! The enemy does not dictate how we fight. Americans set the fighting tempo. Not them. I advise DoD to rip up that paper agreeing to no more night time raids. Good work Michael Yon as always. Thank you to DoD for the common-sense helicopter medic policy and for ripping up the agreement about the night time raids. Thank you DoD when you do really change them and really start taking the fight to the enemy.
This commment is unpublished.· 6 years agoI will never forget being left behind with a couple of E6's and a Spc 4 out in the desert with two UH-1H's sitting in the moon dust.
This OH-58 swoops in blowing the moon dust into a brown out and as the air begun to clear a full bird comes walking out of the cloud. He screams at me: "Who is in charge here?" I saluted and said that I guess I was as a wobbly Warrant Officer 1. The full bull said: "Well you get your men and get those helicopter windows covered in camo because he could see their reflection miles away. I explained to him that we had no camo for the wind screens, SIR.
He said the following: "Well, then you damn well better get some buckets and make some mud and cover those windows Mr."
I tried to explain to him that they were plexiglass and that doing so would forever ruin them and that the aircraft probably couldn't even be flown because of the scratching and crazing of the plexi. I also got the two E6's over there to witness the exchange.
He said he didn't give a damn what I thought and to get it done now!
We complied! The aircraft could not be flown again until new wind screens had been obtained, flown in and installed. Costing untold thousands of dollars in material not to mention time and waste of man hours.
In the Army I found many of the Real Live Officers that were not aviators to be elitest idiots when it came to the use of aviation assets. That included my time assigned to a Medical Detachment.
It was always better to be tactical than practical!
Guess things haven't changed much!

This commment is unpublished.· 6 years agoTaliban has no radar. And no aircraft that can flyover a helicopter and take it out. Camo a helicopter makes sense, but it is still a noisey beast. Interesting story--The Shah of Iran, before he was toppled, was prepared to purchase 200 YO-3A low altitude silent night recon aircraft. check website www.yo-3a.com for more information and history on this airplane. And yes, the Army-Lockheed YO-3A in Vietnam had a camo paint job to make it difficult to see from the ground at night.....That may have been an Army 1st...
This commment is unpublished.· 6 years agoAnother great article! That last pic shows the contrast of policy. Medics wear camo uniforms for a reason, why have them show up to the scene in something that makes them easier to see? I am pretty sure that the sound of a dustoff is more important to wounded troops than it having a red cross on it!
This commment is unpublished.· 6 years agoI wish I had more time to write but my conclusion is the Army is filled with Control Freaks. These control freaks are so concerned with their control over things, it is important for them to have control over their assets rather than save a few lives. After all, it's what got them to where they are in the first place. They never took a risk and allowed their subordinates to think for themselves. They are the officers who think they made it to the top themselves and never realize it was their subordinates (junior officers and NCO's), with their FLEXIBILITY TO THINK in tense situations or adapt & adjust to changing situations that aided them to the top because they are egotistical control freaks. If they weren't so egotistical, they might see how this situation is affecting soldiers.
