Greeting to the military community and thank you for your contributions and sacrifices, they do not go unnoticed 
Anyway, I respectfully would like to inquire about Artillery coordinates and language. I am a writer and am currently writing a book on the Iran Iraq war of the 80s. Because I do not know how commanders and field artillery personnel talk to each other, I would like to see if I could get help. I am writing about a platoon that is about to be overrun by advancing enemy mechanized cavalry units, but the platoon commander is ordering that his artillery which is 2 kilometers behind the platoon, fire on the advancing cavalry units. I need to know what would the commander radio in to the artillery units. Would it be, "we need fire on this coordinates?" or what. Can someone simulate a situation just so that I can have an idea and perhaps copy the idea onto my manuscript? Thank you guys in advance and good work!
