Infantry platoons bristle with direct-fire weapons, but everyone loves a grenade. Grenades give ground troops the ability to send a big boom of fire and shrapnel over a wall or hedgerow, inside a window, or wherever else you can wing one. The catch, of course, is that a hand grenade’s range tops out at roughly 40 meters, depending on whether the grenade-hurler tried out for the minors before joining the military.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
