I did some research. The MLRS are deployed in batteries of 3. Each launcher carries 12 rockets. So a battery in the game with 4 slots of 9 rockets is meant to represent a 3 launcher battery. An accurate representation of 1 launcher in game would have 2 slots of 6 rockets each. The launcher's magazine is divided so that it is capable of launching half of it's payload or all of it's payload in each salvo. So it woulb be unrealistic to divide the rockets into 4 slots of 3 in game.
