As it was pushed back, Really heavy fire came down from behind it in the halls. [spoiler]https://imgur.com/a/o2nEB[/spoiler] Four Marines were firing at it from behind, however they all different. One was just in some regular Power Armor (above), one was identifiable as an Apothecary, another a Techmarine, and finally a Terminator. Most of them carried Bolters, besides the Terminator who had a Rotary Cannon (think that's what it's called) in his right hand, and his left had a lightning claw.
