Different strokes for different folks. Military don't obey no civvy rules for nobody.
We flew Hueys single pilot IFR with no SAS, no autopilot, no nothing, just a single ADF for guidance.
In the civvy world, a 212 with a 3-axis autopilot still needs 2 pilots for IFR, along with its ADF, VOR, DME, ILS and anything else they can jam in.
