Probably finger trouble or a training exercise.
I doubt that the officer or squaddie cargo would jack their own aerial limo.
Ther's a J-STARS near him too.
Various diverse assets in the vicinity of a military plane squawking 7500 makes me think of a training exercise.
J-STARS has very advanced tracking/surveillance gear.
It's descending @5-600ft/min normal descent rate.
I suspect that he might have a minor mech/tech or radio problem & he squawked 7500 instead of 7600 or 7700.
This happens more frequently than people realise.
Military aircraft sometimes intentionally use emergency squawks to train the controllers on the ground.
Flying the landing pattern for Travis AFB.
