In a recent game, Simon used his four Sentinels.
I was lucky and managed to take out the two non-flamer armed ones, which reduced his long range firepower, but having said that when the Sentinels did get in range they certainly toasted some of my units.
This one is a flamer armed model.
It also has extra armour.
