Guardians are capable of destroying groups of both air and ground units in a short time. They cannot fire unless mounted.
While the Beta do not have turrets to protect their base, a group of Guardians mounted to a wall serve the purpose just as well

Guardians can shoot both air and ground units
Guardian's ground weapon becomes a long range artillery shot. Best used when defending against large amounts of unarmored units.
