The Hercules is an airborne transportation unit. It can pick up all T1 land units and some T2, with exception of heavy ones, like Fatboy or Tzar. Use it for unexpected unit drops bypassing your enemy's defense line, but don't forget to scout first for any anti-air units. It cannot pick up Commanders—use Hephaestus for that.

Can be used for transporting Construction Turrets, which are otherwise immobile.

Light transports are useful for shifting buildpower around the map, eliminating a lot of walking time for constructors, and delivering T2 constructors to allies in team games.
