Don’t do the Enclave dirty like that, they had actual military staff as a solid chunk of their original population, problem is they kinda went nuts after the nukes went off. Ignoring 76 for a moment it’s kinda implied that the upper echelons on the rig started to go insane a couple decades in possible after the OG population were either dead or elderly. Also they produced Sergeant Arch Dornan which if he is any indication implies they had some level of original military culture at least by Fallout 2.

Hell even accounting for 76 if memory serves right it was the actual military elements who put a stop to the traditional Nazi style Enclave bullshit. Mind you that’s after fucking everything up but hey damage control.
