Wooty, back to your original request
UH-60A's all have the HIRSS, like the L. LIke HA mentioned, the difference between the A and L are the "sponsons" The L's sticks out somewhat more than the A. Since I've been ot of the cockpit for a bit, I'll have to dig out my dash 10 and take a look..
UH-60Q is a mission specific (medivac) A model with a FLIR under the nose.
HH-60L is a mission specific (Medivac) L model with a FLIR. The 507th Medical Company at Fort Hood flies them. Glass cockpit, beautiful. The engine covers say, "Lonestar Dustoff" with the state of Texas between the words. The right side under the engine is the external hoist.
MH-60A/K/L have the folding rapid deployment stabilitars, what I am assuming everyone is callling the straight stabilator. As far as colors, I just saw an L model that was painted Helo Drab, but the garden variety color is flat black. The K models have the high Gull ESSS wings so tthat the gunner doesn't mini-gun the tanks in a "Mad minute" frenzy.
These are the 'Hawks I've seen in OIF/OEF:
UH-60A's The ones I saw were flown by B/158th assigned to III Corps (VIP Flight) and some guard units.
UH-60L's: Flown by 4-101, 5-101, 7-101, 2-4, 2-3, 571st Med, 507th Med, etc, etc...
HH-60L's Were flown in OIF-1 by 507th MED. I think they are spooling up for another play in the sand here soon...
MH-60's Were flown by the those that which we dare not speak their name, for unspeakable wrath cometh from such utterance...:) Matt may get my humor.
Hope I answered your questions.
