As of HotS, massive units could shatter force fields by moving into them, so that functionality has been added to AP forcefields, as well as the vanilla forcefield in the WoL submod.
Tested on Zerg smash+grab; an ultralisk could walk right through the end of the first bridge. Also tested Ravager bile; it could already smash forcefields so nothing has been changed on that end.
