How to unlock the Hammer of the Gods achievement in MAG - Definitive Guide
Just be a Squad Leader and call mortar barrages and cluster bombs (airstrikes). You'll have to call 50 of them to get this trophy. That's quite simple.
Note: When attacking, if you call an airstrike in a zone where the triple-A is still up, it will still count. But it won't be effective at all.
