Yea but before you pack up you want to make sure your area is clear. Usually I won't pack up unless I've moved units forward and know I'm clear for a bit. Listening to the map helps. Another great time to pack up is right after you've won an engagement that seemed to have consumed a large amount of your enemy's forces.
Also, didn't we already establish that the emplacement can shoot while it's packing up, but it just can't auto-fire?
1 M.I. and a pack of Puddin's Pumas would prove you wrong sir.
And yes, I do not know why I defend this. The gun fires, I am happy. Even though I do not use them now, since my brit playstyle has changed since the time I posted the first post.
