The thread's name is "Tutorial: Catching Weapons Fire in mod inspecific fashion".
Author have created this tutorial while working on aimbot detection.
An aimbot is usually used with handguns/shotguns/(sub-)machine guns/rifles.
When he wrote "fire" i think it's obviously that he mean only the weapons listed above and not knife/grenade.

EDIT: while he mentioned explosives/melee it doesnt seems like he tried to detect explosives/melee attacks.
