I’ve seen far better civilian corporate security. They need to keep disciplined 24/7 guard mounts on that, more electronic/mechanical security or both.
At ICBM bases they have both electronic and mechanical. The alarm is sounded in the missile pod where the missileers are located. From there, the security is sounded. Often, its just deer wandering on to the base. But, you have your occasional protester trying to deface the missile blast door.
