how about some little stealthy bugs and a stealthy commander, but they need to eat lots: "the swarm moves at night and burrows deep into the ground before dawn to avoid detection, the only sign of their presence is the destroyed vegetation they leave behind them".

not sure how it works, since i have never used a stealthy army before, but could something like this possibly be used to starve an enemy army?
