@Average Dude  
even if he had airsoft granades, using them like that would make them a 1 use item and they are super expensive.
a granade launcher would be a better choice, but thats a rather rare airsoft weapon.

@Average Dude grenade launchers or normal grenades wouldn't do anything to him, at most it would injure the people and throw shrapnel everywhere, I think a HEAT round from any AT rocket would work better
