EOD officer

I have read that after your training is done, that officers are promoted to O-3 just wandering how true that was. Aswell as what is the promotion rate for them is it fast since they are spec ops or is it average. how did you like your career as EOD right now im a navy corpsman wanting to go into the spec ops world as an officer. and while i was in iraq and africa the eod bubbas seemed like they had alot of fun. Thank you Senior Chief for your time.
Sorry for the late reply. O's are promoted on the regular schedule. No faster or slower. It's mostly automatic until 04.
