One of the worst parts of the game is the way all units act as double-agents for the enemy. Build up a strong army (let's say the 25-man limit for the Marines), mobilise them, & watch a third of the morons find some ridiculous, alternate route to the intended location which divvies up your forces, takes an extra twenty minutes, & completely undermines the whole group.
'Divide & conquer' has never been mastered in reality so well as it has by the morons who manufactured this game.
