If you know me you know I'm a fan of older models most of the time. The guard Sentinels are a big exception. These current models are easily the best version of this unit in the long history of 40k. I'm keen to use them ASAP.
I cooked up a simple back-story for the squad last night. Units 1 and 2 are piloted by a couple of hardened veterans, but unit three is always piloted by a rookie because Unit 3 pilots don't live very long. That's why Unit 3 is so beat up.
This Alt-Terminator got his Power Fist chopped off and replaced with a s Power Sword so he can be a legal Sarge. It worked better than I expected.
