Not hard, I make some myself. You have the choice to use labels for your decals, water-slide decals (i use those) or you can improvise with tape. Now, to actually make them, you would need a template of a full lego body like over here (in the related links section)
And depending on if you want historical accuracy or something to look cool you can try to research uniforms and just edit and draw it on a program like paint or photoshop. Instead of making it yourself, you can just find some online. If you Google "lego army decals" you'll be sure to find some nice ones. For good decals check out Roaglaan on Flickr or whoever you find.
If you need info on actually applying the decals or readying them, i can't answer that now because I don't know what type of decals you want to use. Check for more info on YouTube or google and you'll learn.
Good Luck!
No. People make custom army minifigures though if that's what you're interested in.
A few companies offer custom decal designs that they will print. The companies Build a Sign and Decals Planet are two of them that make custom decals.
Obama Decals, Storm Decals, Jean Grey Decals, and Wolverine Evolution decals Plz!
You will have to hunt around for custom army Legos as Lego themselves do not make modern day warfare sets. You should be able to find Lego army men, guns and sets (or just instructions) for vehicles like tanks at websites like Ebay and Amazon.
There are many websites that allow someone to make custom decals for any business online. Examples include Zazzle, Vistaprint, DecalZone and MrDecals.
