What about allowing buildings to be garrisoned? If you produce a couple of new units and there is no space outside for them to go, leave them inside the building that produced them - the garrisoned units can then attack from there.

This way you won't have newly trained/built units becoming completely slaughtered because they were spawned deep within the enemy's formations.

It's trivial to pathfind from the building to the selected location (ignoring everything but terrain features) to ensure that the unit could normally move from the building to that point. You would want to apply path-length limiting so you don't waste time searching the whole map for a path and to ensure that it wouldn't take the unit 30 minutes to get back to the building.
