Diverse Tactics G10:
Use one of each heavy weapon on a single mission

This achievement requires that you use each heavy weapon at least once in a single mission. Heavy weapons include grenades, rockets, and airstrikes. Grenades and rockets can often be found on the ground in most missions, but airstrikes will need to be purchased from the command center. Purchase/find all three and use them one time each to unlock this achievement.
