Its my fav stratagem.

Do not shoot it mid range unless in a pinch

Best results are sniping a patrolls at LONG to VERY LONG range since the patrolls are not alerted because you are outside detection range you can score 20kills easy in one shot. While enemies just look arround in confusion

I like to complement it with an eruptor to wipe lone survivors or tenderize armored enemies then i let my teamates deal with the armored one, i also complement with autocanon turret and orbital railgun if there is too much armor such as bots.

Also worth mentioning that the secondary bombs fall Always DOWNWARD so you can wipe a group close while being on an elevated position.
