The main character knows how to use the guns or ARMs (Ancient Relic Machines)
I hate these stupid acronyms. Why do people come up with such dumb names ('Ancient Relic Machines') just to get a sequence of letters that 'happens to fit' the context? It might have been cute the first two times, but the joke has long worn thin.
The software I'm writing was given an acronym name. The software is for reading aircraft flight data recorders, also known as blackboxes. They originally considered naming the software
Sensor Calibration And Replay System (SCARS), but changed it to
Sensor Test And Replay System (STARS) because they were afraid SCARS would "leave a mark". That aside, the software wouldn't feel the same without a simple and meaningful name.
