How do the mortars work in this game?
I watched a few people playing mortar sections in Squad and it seemed like the section commander simply looked at his map, put a marker on it and told the gunners to shoot at it. I assume they had maps themselves, or a marker appeared on their screen?
Another lot were far better, with lots of practiced military jargon (albeit somewhat inaccurate) and their bloke seemed to be giving out ranges and proper azimuths, followed by fire corrections mostly in metres but also in mils. Seems like the gunners only had to dial in the alterations and fire...?
I've not used mortars in PS yet, but In Squad, when the squad leader places certain marker icons on the map (I think Attack and Movement markers), all of the squad members get a marker on their compass rose showing exactly which direction the marker is, and an approximate range (accurate to 50 metres I think), so they can move toward it without having to keep checking their maps.
When you use a mortar and bring up the sights, you can therefore orientate yourself to look in the direction of the map marker using your compass and moving the mouse left or right. And then adjust the angle of the mortar tube as desired for the range by moving the mouse up or down. Right-clicking will bring up the optical sight with an on screen chart which shows what angle the tube needs to be (in milliradians) for the desired range.
So if the SL places the marker exactly where he wants it, then it's fairly easy to dial in the range and fire, and then the SL (or anyone acting as a spotter) can watch the fall of the shot and tell you how far off target you are so you can correct. However, I know someone on the forums developed a mortar calculator which you can download and run as an app on your phone. I've never used it, but I think if you tell it what map you are playing on, your current mortar position (grid ref) and the grid reference of the target, it does all the calculations for you (including allowing for terrain elevation differences) and just gives you a bearing and angle to use.
