Most of them are things that you'd say over the radio and probably don't have any meaning to most people and I won't get into most of them.
"shot, over" and my knee-jerk reaction is to say "splash, over".
I used to work with a bunch of other ex-military guys and we all carried radios on our hips at the job. The ex-Army guys would randomly say "shot, over" all the time on net and the rest of us would race as fast as we could to reply with "splash, over". Or at least I would. Maybe they were just messing with me, which could be the case. I was a very broken person at my last job (which is the reason why I lost my job) and I had a lot of problems with PTSD and stress...
Early Thanksgiving morning in 2004 I was conducting a patrol with a section of armor from my platoon. I was approaching an Iraqi Army checkpoint located at a bridge that crosses the Diyala river just north of Baqubah when a whole bunch of tracers came at us from a wooded area somewhere north of my position. I couldn't see anything, but I knew that enemy were in the palm grove so I called for artillery fire into the area. I explicitly state that I wanted HE (high explosive) rounds yet they sent me illumination rounds (giant flares that light up the night sky like it was day), which really made me happy. I loved the idea of negating the advantage that I had with my thermal and nigh-vision optics and providing the enemy with a easy opportunity to identify my precise position.
It was a cold and miserable morning. It was wet from the rain and I spent the rest of the morning stopping and searching random cars as they crossed the bridge. I don't remember what I spent the rest of the day doing, but I do remember that our thanksgiving dinner was phenomenal. The hot chow that was served to us was usually very limited in quantity and shitty in quality, but both the quantity and quality of our thanksgiving dinner was amazing.
