I've recently unlocked the Mortar for the Support kit which I've been wanting to get my hands on to take out pesky snipers. I've managed to get a couple of kills before someone hunts me down and shoots me in the back or I get killed by an enemy mortar. I also have difficulty hitting moving people as the shell takes around 8-12 seconds to impact the ground. I use it extensively in Rush around the MCOMs – both attacking and defending – by firing in the general area of the MCOM and I end up with a couple of kills or kill assists.
It it a good idea to stay in one spot, or fire a couple of shells, move, fire a couple more, move again, etc?
How do I switch between smoke/explosive shells? Or is it an unlock for the mortar?
Is there any point in using it against heavy vehicles (i.e. Tanks, AA, etc?) or should I just use it against infantry and for taking out enemy explosive?

General stuff
The biggest disadvantage with mortars is that you show up on the enemy map as soon as you fire a shot.
put it up, even before you fire your first shot.Assuming the enemy team doesn't have mortars, you can fire a few shots before they hunt you down. But as soon as one of them also switches to mortar it is dangerous to fire more than 2 shots, sometimes even one is the maximum before they counter-mortar you.
Also, if you shot, move, shot, move, and so on, they will be more alert and just wait for you to put up your mortar somewhere. If you do something else in the meantime and set up a mortar after a break of a minute or so, you may be able to fire a few more shots before they are on to you again.
Smoke
You switch between normal shells and smoke using 1 and 2 on PC and Left and Right on dpad. Smoke doesn't need to be unlocked.
Vehicles
You should only use the mortar against vehicles if they are not moving, or only moving in a confined space. For example, on Rush maps when they are defending/attacking an MCOM and only move back and forth a few meters, mortars can be useful.
Take on for the team
If you are a team player and don't care about dying often, spamming the MCOM with a mortar can decide over win or lose, so this is really one of the good uses for the mortar. You don't lose points when dying, but the smoke you deploy on the MCOM or the enemies you kill that are defusing or arming it can make a difference.
