Start up Data Hive, rally point Alpha, on any difficulty (obviously Easy would be the best). It may be worthwhile turning on the Catch skull to increase grenade drop rates, but it's not essential.

Proceed through the level as normal. You'll quickly meet a police officer and activate a trapdoor of sorts that you jump down into to go down a level. Drones will come out of this hole but you won't have a flame grenade yet so just kill them and move on.

On this lower level you'll soon come across 3-4 invisible Brutes. These are the guys who drop the flame grenades. Kill them, stock up on the grenades, then proceed through the next door or two and more Drones will come swooping out at you. Hit any of them with a flame grenade and achievement unlocked.
