What drew me in was JC's latest mission. I gave it a try last night. Note that this is my first time commanding any other troops in the game.
There's very little I did right here, though I did get close to the enemy and on a flank. A bit more learning and a conversation with JC to pick up some tips helped a lot in subsequent attempts! My biggest problems here was first, not knowing enough about controlling my squadmate, and so not putting him in a mode to really help me, and second, moving in the end into a far too exposed position. I have to remember that I'm not a tank.
