It's baffling that the USMC is sending you to San Antonio with little to no idea what happens after IFS. Alas...
From the cockpit at Pueblo, the next stop is the RPA Instrument Qualification Course (RIQ) at Randolph. You will fly a watered down T-6 simulator for about forty hours of in-cockpit training, learning how to fly basic contact and instrument missions. You'll learn how to fly ILS, VOR, and GPS approaches to real-world airfields around the San Antonio area. This is on top of roughly 140 hours of academics. The final stage, developed uniquely for RPA pilots, is known as the RPA Fundamentals Course, also at Randolph. During this final stage of undergraduate training, you will gain insight into the basic operation of "sensors, tactics, air tasking orders," and the multitude of skills needed to ensure success transitioning to an RPA airframe. There will be more death-by-powerpoint, but a little more interesting.
