The Shotja works well both as a defending unit and attacking support unit:
On defense it is extremely effective at picking off light units, and pairing a squad of them with Point Defenses works very well, the turrets supplying cover for the lighter armored Shotja's and the firing rate necessary to keep from being overrun, and the Shotja's provide a higher intial shot damage and longer range. They are also effective when holding their own position from higher ground, such as picking off bots from a cliffside.
On offense they play the same role the FA Sprite Striker did: Fire support and commander removal. However, don't use them as one would use Cybran or UEF artillery to damage swarm of units, as the Shotja lacks splash damage, and always leave a small amount direct combat units to defend them, since Shotja's will never win a head to head fight with any land combat unit, including missile launchers on some occasions, due to the Shotja's slow movement speed.
Deploy Shotja's wisely, as they can't outrun any unit whatsover, including ACU's.
