Imperial Fists Castellan with heavy bolter
Here we are, getting into Horus Heresy again and going to make another Alexi Polux army. I will have small 500 points of worth force as Hammerfall Strike made of Castellan and his 20 men. Ten tactical legionaires and ten heavy support squad guys with heavy bolters, because Imperial Fists. And they will drive in Rhinos.
So starting with Castellan Alfonso Pulmafinga, a veteran of many finger-pulling pranks and farts. Enjoy!
