Thanks for your comment, I find all this military stuff really interesting since it's very serious stuff so they most likely always have good reasons (like not getting killed or killing your friends) for why they do what they do.

This reminded me of this scene (even though it's not about using "repeat" in the wrong context) https://www.youtube.com/watch?v=B9xg2-6JDL8

and about a section in the book Chickenhawk where the protagonist (Huey transport pilot) is at a artillery site and realizes how everyone is basically fighting their own war.
