Ok so I understad the meanings and numbers for infantry, platoons squads battalions company's ect. but I do not quite understand the numbers for artillery. I do know that they are called batterys, but how many guns are in them,or how many guns, or batterys are there for a battlion of Marines, or just how do the numbers work for artillery? I tried my best to write this so you can understand what im asking, so i hpe you Marines get what im asking!
