Armada 1 Assault Ship

The game Star Trek: Armada has two kinds of ships, that can be considered as assault ships:

Depiction Name
SuQ'jagh
Cube

While being definitely also a heavy cruiser, the fact that it's special weapon, the Commando Team aims more at capturing other units and vessels makes the SuQ'jagh more an assault ship. Same goes for the Cube. It's Holding Beam is definitely meant for taking over opposing structures. Still it is also the most powerful battleship.
