This thing reminds me a lot of the Goblin...
No kidding. It's like someone took the original Goblin and made it better in almost every way, except price I think.
More armor, four times the troop capacity, all energy armament, better main gun, better speed, slightly lighter.
With the capabilities a Dark Age Battle Armor squad could have, I think the PPC's minimum range would be far less of a downside than it would on the Goblin back in the Succession Wars. Most medium BA can cover 3 hexes in some manner without too much issue, so anyone charging a Hasek to get under that minimum range is putting themselves at risk of the Hasek's ankle-biting friends.
