Scouts are the weakest enemy units in the game. Any unit can destroy it with one hit. You will see a lot of them early on, but as during later stages they will be a rare sight. Scouts are the cannon fodder of The Crimson Alliance. After completing the second map, the enemy realizes that they're getting nowhere using scouts and start sending more advanced troops, like tanks, stormtroopers and rocket batteries. Despite this, they still appear occasionally. Becareful not to lose track of them, as they can still pose a threat (to weakened units). They also appear quite commonly as units dropped for the enemy dropzones and can become a pain when you have to bring back an APC (the best unit for quick operations) to get rid of them.
