Just make sure you are aware of how ECP works in regard to Active Duty.
All ECP cadets commission into the Reserve component after completing their associate’s degree and serve in the Reserves or National Guard while they complete their bachelor’s degree at a follow on four year school. If an ECP cadet wishes to compete for active duty, they must request to revoke their reserve status during their sophomore year . If that gets approved, they will then compete for active duty during their senior year along with all the other ROTC cadets for that year’s cohort.
That's the kicker "If that gets approved"
There are not many, maybe one or two, on this forum that have gone the ECP route. The most visible person here was told the same as the statement above, I believe that out of their class only a couple were recommended to compete for active duty and I am not sure either was approved. It can change every year, what your told when you start may and can change without warning.
If you are at all interested in Active Duty when you commission I would highly suggest you rethink ECP.
