In the snake eyes video the mod used is Troops for Lockon by Tomcatz and not the ground Crew mod v1 neither V2.
In fact, i think like you : Troops are pretty difficult to find and to target, they have huge guns and are shield like a LAV-25 or a BRDM-2... Some pretty respectables enemies ^_^
To come back to the ground crew discussion, i have read on http://www.lockonforum.de that the matter with the texture is known. I beleive that i understood that is because there is a conflit with another object which use the same texture. I made some test with 1 pice of the ground crew and 1 aircraft but the pb still remains for me :-((
