Commando
The Commando is a versatile and amphibious "paratrooper" bot, which needs proficient control skills to be successful.
It will drop out of a transport when it gets destroyed.
Its cannon fires rapidly with splash damage, and it regenerates its own health faster than most units, but it primarily excels as a minelaying saboteur and spy.
Use mines and its weapon to weaken buildings, then reclaim them for their full metal value.
__It's able to build a few different units with the second longest build range in the game. It can demolish bases or lay mines amidst enemies even over cliffs or from water onto land, and set cameras in terrain where enemies won't find them.
Commando is the only unit, besides the Phantasm, that can jam radar/sonar from the water.
__Uniquely immune to the Juno missile, it can keep units & structures hidden while providing radar itself. Given its very short jamming range, Move in formation orders should be used so it and your forces all move at the same speed.
