I might be wrong, but here's my rebuttal:
Yes, they may call me up and ask to speak with me, but by Part 91.117, paragraph d, that speed limit doesn't apply to the T-38. The FAA has stated that since the 300KIAS is listed in the T-38 flight manual, that's the speed at which we may operate.
Therefore, I don't think New Rivers' Base Ops / ATC would not have a leg to stand on.
"(d) If the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed."
Many of you folks are way smarter on this than I am. Is there something I'm missing?
When operating in restricted airspace, which it is, you must comply with all restrictions.
