The remainder of my Imperial Guard allies consisted of a company command squad with a mortar and a veteran squad with a las cannon. These two units worked so well together manning the aegis defense line with the Icarus las cannon. Orders like 'bring it down' and 'fire on my target' were especially useful considering the sear amount of terrain that was available this year.
The models are mainly micro art studio 'goblin troopers' with some head swaps from the grot kit and some imperial guard lasguns. The las-cannon was a little more complex but again is mainly just a collection of various bits, including: heavy stubber, grot prod, corpse cart wheels and leman russ wheels. I think they look quite good :)
