Did some digging in the PBOs to see which skins are available.

In the ori_veh_skin3.pbo I found some textures for the Huey (uh1h_ori) with the names:
uh1h_ori_2_specialp1_co.paa
uh1h_ori_2_specialp11_co.paa
uh1h_ori_2_specialp2_co.paa
(I think the "p" stands for personal texture)

The p1 and p11 ones both contain the name "Pusher_1337". If you google this name you'll find some videos showing him hacking (driving around with a tank in Origins and killing people).

Any explanation why we have these files in the mod? Did he make a contribution for that? Having special skins for a hacker is very questionable...
