A.P.C. COUNTERS

To counter something like the APC that drops a unit with a different armor class I would suggest units that do good damage versus tanks and infantries. unfortunately most of these units are high tech units. Artillery comes to mind. Also keep in mind that people tend to use APCs to hold pads because of their huge durability. A juggernaught or artillery can snipe them down pretty fast, as they one hit kill infantries and do good damage to tanks too. Another counter that comes to mind is the Orca Bomber and Inferno Bomber, the flames left on the ground will burn the missile squads that come out.

APCs themselves are very unique units, for example you can't really ION cannon blast them to instantly secure a platform, you still need to take care of the missile squads.
