Losing Your Gun
Speaking of that feeling like your gun is still with you – ex-soldiers actually sometimes have dreams of losing their gun (more like nightmares really) but they wake up and realize that they no longer carry a gun.
Phonetic Alphabet
Spelling out words using the military phonetic alphabet is a tendency that all soldiers have. They will say something like “juliet” instead of the letter “j” and “delta” instead of “d”. You’ve probably even heard them talking right beside you and you had no clue what they were saying.
