Beach Battle

Red team: human, 4 worms.
Blue team: 1computer, 1 worm.
Terrain: Beach

Welcome to the force, Sergeant. I'm Charlie, your missions officer. I'll brief you on each mission's objectives, and I'll try to give you advice all through it. Since you and your team are relatively, *ahem,* inexperienced, you'll be sent on missions which are pretty easy at first. Don't worry, you'll work your way up to the tough stuff pretty quickly.
Your first assignment is to take out a lone thug on the seaside. He is dumping toxic waste into the water. You'll have three of your teammates with you, so it shouldn't be difficult. Dispatch the henchman and report back.
