If you have a culture where everyone thinks they're either commandos, infantry, or police, it's possible you're going to have some customer relationship issues.

Who's the enemy in this model? If people don't fit, do they become traitors?

Language and metaphor matter, and IMO this is a dangerous and rather dumb metaphor.

But over time I think it's as likely to cause as many problems as it solves.
