A neutron bomb, officially defined as a type of enhanced radiation weapon (ERW), is a low yield thermonuclear weapon designed to maximize lethal neutron radiation in the immediate vicinity of the blast while minimizing the physical power of the blast itself. The neutron release generated by a nuclear fusion reaction is intentionally allowed to escape the weapon, rather than being absorbed by its other components.[3] The neutron burst, which is used as the primary destructive action of the warhead, is able to penetrate enemy armor more effectively than a conventional warhead, thus making it more lethal as a tactical weapon.

The question we should consider - is Q being literal or speaking in metaphor?
Does Q mean we are going to drop a bomb or does he mean that the BOMB that is going to be DROPPED will have the effect of a tactical nuke, a neutron bomb or the like in that it will decimate the amassed enemy whilst dealing the least amount of general collateral damage to those people and things in the proximity of the enemy forces?
