The GBU and JDAM Bomb Lock On targeting system is more aligned with the lock-on constraints of the Shoulder-fired missles than a real laser or GPS targeting system used on modern military aircraft. The system engine parameters should be adjusted to mimic the ArmA2 OA/ACE configuration that allows Target Designation from Beyond Visual Range (BVR) and Solid Tone Diamond Lock when the Bomb is within gravity fall physics variables. With a laser target, the higher the aircraft alititude, the farther out the pilot can release the bomb. Same with the JDAM weapons developed by community users through MODs.
