It was a 105 mm AP cannon mounted on a concrete pedestal with a 360-degree fire zone for broad sweep, short-range protection against GDIs armor advantage. This is the staple of Nod's base defense. Nod commanders have several of these around their base entrances and even can serve well against gunboats when built on the coasts. Firepower-wise, they are the equivalent of a medium tank's cannon without the mobility.
