AH 64 questions

Hello there!

I’ve two questions about the ah 64 question.

One:A few days ago I saw on the newsflash about the war in AF. There I saw a AH 64D with other type of engine exhaust. (it looks as an upward version of the HAVOC exhaust) Can anyone tell me what’s the reason of altering of the engine exhaust?

My guess it’s just an bucket with the nozzle canted upward to improve engine performance. But I wander what you think.

My second question is this: This helicopter that I saw in the news had the lighter green camo paint ont it (the same as the CH-47F). Is htis the new standard camo paint? In the past I saw also the grey painted version. Waht’s the reason they changed it from dark green to grey to light green?

thanks alot!
