Do you have any idea how morbid it is to prevent dead bodies from sinking? If you do it for all units, the living units end up ploughing through piles of dead bodies. It's awesome.
Anyway, there is no fast way to do this. You need to look up the modules for SlowDeathBehavior in every unit that you want to prevent from sinking. Then you can set the SinkRate to 0 and the SinkDelay and DestructionDelay to something gigantic.
For vehicles, you need to modify the death OCL, again in their SlowDeathBehavior modules, and replace the dead hulk with an object that lasts indefinitely.
The advanced version of this is to this is to create your own death modules and make use of rubble states.
