Mortars as they are now, are quite powerful, but, very very hard to control.
What if once a soldier with a mortar enters in “launch position” (crouch then press z) and press G for the command map he could see the coordenates of every inch of the map(like 70º angle/270, etc) then just close it, try to aim the mortar at the coordenates and fire? It would be so much easier and fun to use the mortar.
Hmmm, what if we coud place mortar markers on the command map that would then show up when we are aiming with the mortar? That would make it 10 times more useful.
That is a super idea !!! Just splended.
I would think the real world would work like that more or less…
Like figure out your position, look at the map, do some math and fire !
Ofcourse the part about do some math is for the computer 
yeah !
Lol… no computers in www2
Ofcourse smart soldiers/armies would have figured out somehow to do it without computes… like a lookup table or something.
Such that shouldn’t be a problem
They can’t expect us gamers to do complicated geometry every time we wanna fire a mortar :(.
See my other thread about:
‘Calling in mortar’ !
It has some great new/expanded ideas to solve all these problems and add to gameplay
