I can't do much in terms of in-game screenshots, but I've played the console versions of the Ghost Recon games up and down and know them like the back of my hand, and I can write some descriptions and add weapon pics to them.
Edit: I've begun work on the page for the first Ghost Recon game, but I can't seem to figure out how to get everything to line up properly.
See for yourself what I mean:
