Artillery
Standoff fire against fortified positions and FOBs.
Artillery hits fortified positions and enemy FOBs from a range you can survive. The SPH-2 is WARDOGS' self-propelled gun, a late unlock around Career 90. See the artillery guide.

AE Gaming runs organised WARDOGS every night with free comms, a planning map and a base builder. Reading is half of it, the other half is a squad.
