If there was EVER a time when you could skip the military and enjoy faster career progression, this is probably it.
That said, if at all practical I would still hang in there at this point since there are a variety of benefits, tangible and intangible to be had in the military.
You might consider a carefully thought out talk with unit leadership, along the lines of you need to get your civilian career going as well and the holding pattern is interfering with that. If you already had a regional job, that would be one thing.
Also note that the 750 hour ATP requirement for military only requires:
1. Graduate from military flight program
2. Have 750 hours total
The 750 hours does NOT have to be all military flight time.
