Of course limbs won't be covered :P And yes, someday I'll do that...
With small rounds I mean the 9mm (Glock 19, STK CPW, P90). The .45 ACP (M1911, TDI Vector) and .44 Magnum would do damage.
With bigger rounds I mean the 5.56 NATO (XCR, SA80).
With sniper rounds I mean the 7.62 NATO (G3, M21, M700).
And I don't think I need to mention the other used rounds in this pack? :P
Only 1/2.
P90 fires 5.7x28mm.
Also, Dragonskin isn't super duper "omg stop all dah bullets" as it's advertised. If it were, the army would be fielding it. It failed certaint test, provijng that it doesn't actually stop full penatration. It also weighs 20 more pounds than the interceptor so, there should be some agility loss if you do add it.
Currently, the IOTV is the standard vest for the Army in Iraq, the Intereceptor was thrown out awhile ago for the OTV and then that for the ITOV. I'm not sure what Afghanistan uses because, they use a different camouflage. The CIRAS is standard for Force Recon and possibly MEU. The actual standard for marines is the MTV, Modular Tactical Vest.
I personally think that my idea is better but, it's your mod.
