500 point army gruntz: Commonwealth Navy

Hello, the next army for Gruntz that I am working on is a Commonwealth Naval force. It weighs in at 499 points. I will not bore you by listing all the damage and soak etc. It is designed to be a mid tech level groundpounding army, ideally suited to intervening in anti piracy campaigns, and mining outpost defense situations. As such it is fitting that it should first battle the Rim Defectionist, house Portacollis raiding party.
The army is 80% finished at this point, I only need to finish 24 infantry grunts, a commander figure, and 2 specialist mecha figures( fenrir battle armor suits from mechwarrior). Once done I will finish a little alien Flora and have my first battle of Gruntz.
 Details of the Commonwealth Naval  571st expeditionary brigade.

    these models are towed gun carriages to be towed behind each APC. I paid for wheeled mobility  when creating , so as not to use up a transport slot on the APC.

 primary battle plan is to have 3 APCs advance on objectives each carrying 2 squads of marines and towing an AT heavy laser. Each APC will have a light tank attached as an escort.
the medium tank will work independently(paired up with a specialist mecha fire support)
the heavy tank will work independently(paired up with the other specialist mecha)
 the commander will flit about with his jump pack trying to help without getting KIA
    will post some pics soon, as all the vehicles are done
