This selection of pics ( or rather variants of one pic ) proves which effects can be achieved in Adobe Photoshop CS3 when working on layers.
Lieutenant Colonel Pussycat is wearing 4 different US Army uniform types, including 3 retired patterns ( 1-3 ) and the currently used one ( 4) :
1 - Desert Battle Dress Uniform ( DBDU ) used in 1980s [link]
2 - Desert Camouflage Uniform ( DCU ) , retired in 2005 [link]
3 - M81 Woodland camouflage [link]
4 - Army Combat Uniform ( ACU ) , currently in use [link]
I intentionally drew Penelope Colt M1911A1, despite it was replaced in the US Army by Beretta M92FS - I heard that the Italian 9mm Parabellum pistol is criticized for its low stopping power; besides, depicted 0.45 ACP is Penny's own weapon, not standard issue. Helmet worn by LtCol Pussycat has to be PASGT [link]
I hope my pic illustrates the differences between those four camouflage patterns in easy-to-receive-way. Especially since I have seen people, who keep mistaking those obviously different uniforms and draw them in wrong way.
I would like to thank
for advising me about the patterns. EDIT: I modified the ACU version as advised me. Thanks buddy !
