Is there airsoft alternitives, besides firing your gun?
 

What I mean is a different to get someone with out firing your gun.
Ex. Claymore

Yes there are claymores, grenades, rpgs, 40mm grenades and rubber knives.

"Bang" rule if you're below MED distances and get the jump on your opponent first. If they don't call themselves out then you can shoot them.

Grenades (depends on grenade rules and such)

Rubber Training Bayonets/Knives

Sometimes throwing BB's at your opponent or using a McD's straw and firing a BB from that.

BB Claymores, BB Showers, BB Mines (or "flour" mines), etc.

Meat shield.

Made my day

Bayonet charge.
