Squad Leader 101
As a Squad Leader you're in command of a squad which you can give orders to, some of this order are: "Locate the enemy" "Attack this position" "Attack from the flank" "Request artillery support" "Request armored support" (Notice: You can only mark targets for artillery and armored support, but it is the Radioman duty to actually call in sayd support on the target, without a Radioman your marking will be pretty much useless as there will be no one to send the coordinates to the artillery or amored unit in question) As a Squad leader giving the right orders can save your squads, just like giving the wrong orders can lead them to bad outcomes, so make sure to always have your squad well being as your top priority, as their survival means your survival aswell!
