What did WE actually get in the DLC?
 

I looked everywhere for actual details and can't seem to find any at all.

Yes I know I actually got the bonus DLC because i have the BBQ mission.... but it said we got bombs that can flatten whole city block and a for the motherland charge and all that crap.... where is that stuff located and were / is there a list somewhere I can view of all stuff acquired?

The for the motherland charge is the 5th(?) hero call in for the USSR in MP. The Goliath, AVRE mortar, Sturmtiger, dynamite are pretty damn good at levelling buildings. It says exactly the same things on the Steam store page for Assault Squad. The DLC added new MP maps. There is DLC coming out next week with new defensive skirmishes which will have more units to call in than the current skirmishes
