ahhh yeah, I don't sit by the mortar in bf4, unless it's just a quick few shots. was more talking about bf3 where you were stuck like a lemon!
I just found I'm really impatient and it doesn't load fast enough so just forget about it and carry on with my game, never to be used again xD
One thing I've noticed.. (may constitute a tip
![Eek! :eek: :eek:](/styles/default/xenforo/vbSmilies/Normal/eek.gif)
When you've exhausted the mortar, later when you select it again, it will say 0/0 for the ammo. If you then actually use it it will suddenly say 4/1. I'm not sure how long it takes to reload TBH, and I think you need to replenish by sitting on an ammo box* which shouldn't be an issue as you are support anyway.
* Not tested, it may just magically replenish after a while.
