I believe the armed forces have been ‘integrated’ since Truman’s time as President.
I don't think the point is inclusion. You are right that it has been achieved for a long time. The goal is division. To destroy the old system, and in doing so to "prove" that it never would have worked. The left thinks that people will be so desperate for order that they will grasp for the "new" system. It is an Alinsky tactic.
Sure. Never mind the bloody fights that took place for years afterward as everyone adjusted to the new situation.
Now we are expected to add ladies to front-line combat units and openly-serving fruits throughout the service and trannies in our formations. An pretend that everything is just wonderful.
Can't see how that might be slightly disruptive to our missions?
