LOL! The sims depends on the modders. Really.
I bought Falcon 4 ages ago, but i patched it with mods that real
viper pilots had a hand in developing. So a lot of the stuff (at
least unclassified ones) are as real as simulations can get.
In the case of CBUs, not only can u decide how many to drop a time,
eg, singles, pairs or the whole rack at a time, u can also set the
release pulse. Meaning, if u were to pickle the whole rack, the
timing inbetween each release, eg, 1 sec apart, etc. And u can set
the release altitude of the cluster munitions.
All these come useful when u need to carpet a whole area.
