Technically, the A series are not TSF, but TSA (Tatical Surface Attacker)
The A-6's are submarine tethered as well, meaning they are attached to one sub per A-6. They also have shit loads of weapons, and are normally deployed as beach head clearer. They have claws for close in combat as well. In general they have enough dakka to turn any BETA into cream, especially up close.
