Well in RTS games, units can be your enemy or your ally depending on the faction you choose. For the sake of your thread, let's pretend this is my enemy instead of one of my favourite units.
I present to you, from the Black Templars mod of Dawn of War Soulstorm, the Land Raider Crusader.
From Lexicanum, "The armament consists of 1 twin-linked Assault Cannon, 2 sets of Hurricane-pattern bolters in the side sponsons and 1 pintle-mounted Multi-melta. "
"Hurricane [pattern] Bolters are a set of six co-axial Boltguns."
