This is a non-exhaustive list of some common ‘quirks’ or habits that can give away a character’s military experience. Wrote it up for myself and it’s particularly useful when I want to show instead of tell. These are based on first person accounts from several vets! Thought others might like to use it too for a reference :D Ones with * or ** came up particularly often.
Notes for writing Frank Castle. )))))
I'll add that military is generally very dismissive of police.
