A weapon simulation system is used to correct the misalignment between a laser of a simulated weapon and an aim point of the simulated weapon. A compensation offset profile and a compensation angle profile are stored in a weapon controller card in the simulated weapon identifying the misalignment of the laser module in the corresponding simulated weapon. The compensation offset profile and compensation angle profile is transmitted from the weapon controller card to a central computer, where the central computer calculates the aim point of the simulated weapon using said compensation offset profile and said compensation angle profile from said weapon controller card. The position of the simulated weapon with respect to a screen of the weapon simulation system is further calculated using an RFID reader in electrical communication with the weapon controller card and at least one RFID tag positioned in a fire line mat, which transmits the position information to said central computer.
