Laboratories: Special structures, that after you finish researching, you should build them, so they will gave you new technologies to research depending on each structures you gonna build.
Never implemented (as Zarel said) because having different research facilities for each type of research was deemed overly complex. Warzone is a strategy game, not "a research-facility-whack-a-mole game" rule.
This might be useful to stop anyone from research rushing, but people would hate this.

NO, HORRIBLE IDEA.
