No, we did worse to them than decimate them. In fact we did the opposite of decimate them, only about one in ten of them finished the war alive.
Think of a 20 ton drone, immune from grenade and rockets, can maneuver over rough terrain, is armed to the teeth, cannot be breached and it just entered your town looking to kick some serious Muzzies butt.
And when it is finished, it can move to a shoreline, go into the ocean and swim out to its mother ship.
Now picture 20 of these things being offloaded by a ship offshore and landing in, let’s say for arguments sake, Somalia.
