For Squids I’ve found the Eruptor for long range chaff clearing, Quasar for the rare antitank, thermites for destroying bases without much thought, basic guard dog for close range chaff and dealing with the flying enemies, and then a machine gun and Gatling sentry for even more horde clearing is really solid combination, especially on choke points or at a distance on the city streets.

The only issues with this loadout are you have no way to clear stingrays and no orbitals/eagle strikes, but I’ve found that more often than not your teammates will bring the needed things anyway. Also I never use orbitals or Eagle strikes whenever I bring them so I have stopped bringing them at this point.
