Warfare enters a new dimension with the attack from above, transporting war up in the air. Early on, archers besieged with devastating incendiary arrows, and long before airplanes were invented, smart medieval army commanders designed rockets. Bomb attacks have become a significant part of vicious war tactics since WWI, and as A.I. becomes increasingly independent, war drones could soon autonomously decide when to strike.

Melee is likely the most original type of close combat, but over time, armies have developed more effective close combat weapons. In this episode, experts test the physical and psychological impact of the three most important melee developments of our time. The Roman short sword (the gladius) and the medieval war hammer both cause severe damage, while bayonets rely on the deterrent effect - but an exoskeleton gives superpowers to the soldiers of the future.
