From Interactive Magic:
Assume the role of Marine Battalion Commander and lead the Marine Corps to victory through 3 campaigns and 15 standalone scenarios. Like the Marines themselves, you'll have to be prepared for anything. You and your forces may be called upon to fight in arctic wastes or desert sands, to storm a beach and clear the way for allied forces, or go toe-to-toe in armored combat. To aid you in your task, you'll have command of a vast array of infantry, armored vehicles, and air support, with forces ranging in size from a single company to a complete battalion. The game is played from an overhead view, so you can manage the placement of your troops. You can also bring the battle to a friend via head-to-head modem, network, or Internet play.
