gps target
how does a mortar crew exactly pinpoint an attack a target ? do they use gps?
Mortars and Field Artillery use many of the same priciples as far as target acquisition goes. By that I mean, actually identifying the target’s grid. As far as how you impliment them and specific weapon characteristics go, they have a lot of differences, but that is a different question.
First off, you have a military map. They are set up with the Military Grid Reference System (MGRS). On that map, imagine point A is where your mortars or artillery are located. They are beyond the line of sight of the target, ideally (can’t see the target) but they use GPS or a survey specialist to tell them exactly where they are. Secondly, you have the maneuver element. That is the Infantry, Armor or Cavalry who is either making contact or preparing to make contact with the enemy. Soldiers are trained on a basic fire mission, and all NCOs are supposed to be able to execute a fire mission. Units today also have the added tool of specifically trained Fire Support Specialists (13F) integrated down into platoon level. This maneuver element is at Point B. The maneuver element (the observer at point B) sees the target at point C.
(Take a piece of paper and draw three points. Put B and C fairly close together and A farther down the page)
Now, the observer’s at Point B are also using GPS and laser rangefinders and other tools to figure out exactly where the enemy is in relation to them. One way to do it is for the Observer (Point B) to call the mortars/artillery (Point A) and tell them exactly where they are. The mortars/artillery now know exactly where two points of the triangle are. They can draw a line from point A to point B. (do that) Now the observers at Point B, tell the Artillery/mortars the direction the enemy is and distance from point B. The artillery then calculates or plots where Point C based on where point B is. (draw a line from point B to point C since you have that information now) Now that the guns know where they are, where the observer is, and where the enemy is they calculate that last line we’re missing. It’s called the gun-target line and that tells them exactly where the enemy is in relation to them so that they can make the proper adjustments to their guns and hit the target on the first attempt.
It’s the same stuff you do when you’re playing with triangles in high school level geometry. Well drilled units can identify a target, send target information and get rounds down range in under a minute.
