MLRS HE ammunition impact area

[Robo76]

I added MLRS rocket launchers and cluster munitions to the MP mission. During testing, I found that the dispersion - the impact area is unrealistically small. I was unable to find the specification for the M26 rocket with the M77 DPICM bomblets warhead. Just as the height of disintegration can be changed for clusters dropped from aircraft, it is certainly set in a real MLRS. Can the impact area of HE ammunition be increased to make it look more realistic? In its current state, the area is so small that it does not even make sense to use the MLRS.
