I was wondering how often CG Reserve Port Security get's activated? I know there isn't a set standard, just wondering from personal experiences
All depends on the needs of the service and what is going on in the world. I guessing you mean a Port Security Unit and not just a Port Security Specialist.
If you are looking at a Port Security Unit as a place to drill, you should contact your recruiter so you can talk to the local PSU and find this info out. CPO Kalbach
