I was in the US military. We all joked, in ways that probably shouldn't have been jokes, that we would "trip" on deployment to the "zone" causing trendily fire accidents for the least like members of our team.

Being US military didn't make it right, we were effectively deciding who we would kill in an effort to make the team more cohesive. That never set right with me, and I still remember the joke (but maybe it's not a joke, joke) to this day.

Don't look to the military as a model of good teamwork. Sometimes it is, sometimes it isn't. One cannot pretend it's the right model to follow.
