Maybe just I got screwed but dose anyone else not have the certification for light fragmentation grenades? First off they didn't mention anything about this C12/C22 thing and now i cant use C12s, which I have a back pack full of. If I would have known about these changes I would have told my weaponsmith roomate to wait untill Int. Munitions to use the crates of war head fusing mechanisms and light warhead mechs. I gave him. I guess I'm just sol for now. Oh well grenades aren't that good anyway.
