I know there are MLRS with HE ammo. There have been and there still are. Now, I admit I don't know for USA in specific. As an example Greece IRL has "HE", CM and those other larger ones for the MLRS, I forget the name. In the game there is only the HE option. But that is not my point. I was talking about other countries with the MLRS system (not any type of rocket system) that for (I am not sure if it is a recent change) some reason they appear to have only CM for them.
I may sound judgmental or angry, I am neither, just discussing it.
