An important step in refining the 'modern military', was acknowledging that members become too comfy, too entrench.

So every 2-4 years, service members are snatched up from their current duty station, and sent to somewhere they have little to no input in picking, for the next 2-4 years.

Otherwise, it gets to be, 'This is my/our base/command'. And these are heavily armed, seriously able-bodied people.

A parallel situation is the norm, in 'online communities'. It's an important factor, limiting the growth & evolution of the culture. The main difference from the military is, 'The pen is mightier than the sword', and they use their brain instead of their brawn.
