Method of Engagement 6. Method of Fire and Control Elements of Call for Fire 1 Identification - you use the call sign of who you are trying to contact and then use your call sign. de= this is. Elements of Call for Fire 2 Warning Order- This element consists of what type of mission it is. AFIS 1. Adjust Fire 2. Fire for Effect 3. Immediate supp/smk 4. Suppression Elements of Call for Fire 3 Target Location- There are 3 methods for target location. 1. Grid- MGRS, min 6 digits (may send 10 digits), Altitude. 2. Polar - Direction, Distance, Up/Down (Change in elevation). 3. Shift from known point - Direction, Left/Right, Add/Drop, Up/Down. Elements of Call for Fire 4 Target Decription - SNAP 1.

Ammunition- High Explosive, Point Detonation 3. Trajectory- Low and High Angle. Low angle is standard. Elements of Call for Fire 6 Method of Fire and Control - WAT 1. When Ready- Less control, faster response, standard method of fire and control. 2. At my Command- Able to mass fire, better effects, moving targets. 3. Time on Target-Standard is +/- 3 seconds the rounds will impact with rounds complete. What is the Standard Method of Target Location? Grid What is the Standard Trajectory for Artillery? Low Angle What is the Standard shell/fuze combination for mortars and artillery? High Explosive (HE), Point Detonating (PD) Which element of the call for fire do you specify ammunition? 5th element, Method of Engagement What is the purpose of direction? The purpose of direction is to orient the Fire Direction Control to the observer's view of the target. Five Rules of Direction OMG 10 4 1. O (Observer to Target) 2. M (Mils) preferred 3. G (Grid Direction) 4. 10 (Nearest 10 Mils) 5. 4 (digits) Polar Call For Fire *Fire Direction Control (FDC) needs to know your location prior to Call for Fire* Direction (Nearest 10 mils) Distance (Nearest 100 Meters) Change in elevation (If 35 meters or greater send in increments of 5 meters. If less than 35 meters disregard.) What does the fire direction center (fdc) need to know prior to polar MSN Call for Fire? Observer's Location What increments do you send direction? Nearest 10 Mils When sending distance, you send it to the nearest Nearest 100 meters Grid call for fire If firing an adjust fire grid mission, the FDC requires a direction (nearest 10 mils) from the observer to the target either with the Message to Observer (MTO), or prior to the first correction. What is the minimum number of digits sent with a grid mission? Six digits (FDC can take up to ten) When would you announce direction when conducting adjust fire, grid mission? With the message to the observer (MTO) or prior to first correction. What are the four parts of the Message to Observer (MTO)? 1. Call sign of unit(s) to fire. 2. Changes to Call for fire. 3. Number of rounds per tube in FFE. 4. Target number How is the term SHOT used? The term SHOT is transmitted by the FDC after each round fired in adjustment and after the initial round in the Fire For Effect (FFE) phase. How is the term SPLASH used? The term SPLASH is transmitted by the FDC to inform the observer when his round is five seconds from detonation. How is the term Rounds Complete used? •The term ROUNDS COMPLETE will be sent when the final round in the fire for effect phase is fired. What is Spotting? Spotting is the number of mils measured between the target and the impacting round. What is the Observer Target (OT) Factor used to determine? the Left/Right deviation correction How do you determine the OT factor? 1. Divide the distance from the observer to the target by 1000. 2. Round to the nearest whole number. 3. If the decimal number is .5, round to the nearest even whole number. 4. If the distance is less than 1000 express OT factor as decimal. How do you determine the deviation correct? To determine the deviation correction you must multiply the spotting times the OT factor (OT x Spotting = Deviation Correction Successive Bracketing Should be used when observers are inexperienced. The goal is to establish a bracket, that is, one round over and one round short of the target. Four Parts to the End of Mission (EOM) 1. Refine (deviation +/- less than 30, range less than +/- 50) 2. Record 3. End of Mission (End of mission, Tgt. #AA0001) 4. Surveillance (Tank Destroyed) When do you send your location for a polar msn? Before you initiate the call for fire How do you calculate deviation corrections? OT Factor x Spotting = Deviation Correction When would you not send a deviation correction? When correction is less than 30 m. What is the standard trajectory for artillery? Low angle What is your OT factor when you target is at 2700m? 3 When would you send your direction for an adjust fire, grid call for fire? With the Message to the Observer (MTO) or prior to the first correction. What is the book reference for call for fire? ATP 3-09.30 (6-30) Name the six elements of the CFF. Observer ID, Warning Order, Target Location, Target Description, Method of Engagement, Method of Fire and Control. You identify a vehicle moving toward a road intersection. Since you do not know when they will get to the intersection, your Commander urges you to do an At My Command mission. What element of the CFF is At My Command in. Method of Fire and Control. In a CFF you send Distance to the nearest ______ and direction to the nearest ____. 100 meters, 10 mils. Based on your target description your Commander recommends you request DPICM. What element of the CFF will you make this request? Method of Engagement Using Successive Bracketing Technique, The last adjustment you sent the FDC was Drop 200, The next round is a direct target hit. What is your next transmission? Fire for Effect (FFE) You estimate the Observer Target Distance to be 2600 Meters. What is the OT factor? 3 Your first round impacts. You measure 30 mils left of target and estimate the round to be about 300 Meters short. You estimate the distance to your target to be 2500 Meters. What is your correction? Right 60, Add 400. You sent a Grid CFF. The FDC just sent you the MTO. What additional information do you send the FDC at the end of the MTO or before the first correction? Direction 9.Your elevation is 1050 Meters, the target elevation is 1150 meters. The direction to the target is 5830 at a distance of 3200 Meters. For a polar mission what is the second transmission? Direction 5830, Distance 3200, Up 100, Over. 11.Your target is about 400 Meters from your location. You should announce _________in the_______. Danger Close, in the Method of Engagement. 12.The estimated range to your target is 2200, you spotted the round 10 mils to the right what is the deviation correction? No deviation correction sent 13.If you are doing a Polar Call for Fire, what information must you send the FDC before you send it. Observers Location 14.If the Method of target location in the first transmission is not given, What is the Method of target location? Grid 15.You are on an established OP and you initiate a Call for Fire. What will the first transmission consist of? Observer Identification and Warning Order. 16.When do you send a change in Elevation and to the nearest what? If the difference is greater then or equal to 35Meters, to the nearest 5Meters. 17.Your elevation is 455 Meters. Your target is at 475 Meters, a direction of 0190 mils, and distance of 2300 Meters. The Grid to the target is NV . What is the second transmission for a Polar Mission? Direction 0190, Distance 2300 over. Why do you send direction to the FDC? To Orient the FDC to the Observer's view of the target. 19.What element of the CFF do you give the Type of mission? (i.e. Adjust Fire or Fire For Effect). Warning Order 20.In a CFF what is the standard method of Target Location? Grid 21.How do you determined the OT Factor? Observer target distance, divided by 1000, expressed to the nearest whole number. If it ends in .5 then express it to the nearest even whole number, if less then a 1000 keep as a decimal. 22.In the Message to Observer, how many elements are there? (do not count the Direction). Four 23.What is the minimum number of digits for a grid mission? Six How many elements in the Call For Fire Six What is Danger Close for Mortars and Artillery? 600 Meters or less 26.With respect to range corrections, you are initially attempting to establish a _____ when using Successive Bracketing. Bracket 26.What do you send the FDC after you completed your mission (destroyed your target)? End of Mission If the distance to your target is 3200 meters, What is your OT Factor? Three What is the Minimal deviation correction you can send? 30 meters What is the formula to calculate deviation corrections? OT Factor X Spotting.
