Grenades are the cheap version of the grenade launcher. With a smaller impact radius than the grenade launchers and rocket launchers, they are still very efficient at destroying buildings at close range. Use them against people hiding in their small fort if you are close enough. You can also drop them down a hill. The further away you are from a grenade, the less damage you will receive.
Ammunition used: Grenades
