The Stormsiren is one of the only Commanders with a Tactics value of 3. This gives her a few more options than other Commanders. She also creates an additional Tide Pool piece at the start of the game, giving Companies that contain her even more battlefield control.
Her Grasping Tentacles attack has a good Strength, but if she manages to get you in water that's where it really shines. This is made easier for her with the use of Siren's Call, which lets her move an enemy Fireteam. Since Commanders get a free Morale Action, she can use Siren's Call and still make an attack that turn.
