When a steel plated hull is fitted with controls on the inside and tracks on the outside, it’ll become an armored amphibious personnel carrier that can get troops in and out of any combat zone, even if it has to go through snow, sand, or water to get there. After a piece of aluminum is welded and wired, it will become a robotic arm that can punch through walls, look for suspicious objects, and carry deadly explosives safely beyond the blast zone. A life raft may seem simple, but it takes days for rolls of watertight fabric to be cut, sewn, and fused together.
