Not bad ideas you have here. Tho a field jacket doesn't really count as light armor perhaps the Vietnam era flak jacket would have been more appropriate.
The Modular Tac. Vest can also be modified for the medic armor as well just add a MOLLE backpack with a red cross emblem on the pack.
Good point Alistaire, maybe you should stay awake more often so you can remember to keep your manners, eh? People put TIME into making their graphics, as you did in yours. Regardless of whether you like it or not, you have no right to cuss them out like what you usually do. Just saying.
