Cannon Platforms
What is the minimum QE that is considered "High Angle"?
800 mils
M30, M31, and M31A1 are considered Precision / Guided Munitions. What guides them?
GPS
Two different Methods of Control that can be used on Cannons is At My Command, and Do Not Load. What is the difference?
AMC = Round is in the tube, tube is oriented on correct Deflection and Quadrant, just waiting to pull the lanyard
DNL = Round is NOT in the tube, it is being held just outside
What are the three methods that can be used to calculate Rocket Safety?
Op Area, Point to Point, Firing Point
What is the US Army Doctrine that covers The Field Artillery Cannon Battery?
ATP 3-09.50
During RSOP, how far away should the Cold FDC emplace from the rest of the gun positions?
1. 500m
2. 1x Terrain Feature
What is the MINIMUM effective range for HIMARS?
15km or 15,000m
TOT is a special instruction that allows rounds to impact at a specific time desired by the observer. How do we calculate when to fire?
Find the Time of Flight of the mission, subtract the TOF from the TOT, subtract an additional 5 seconds for transmission time.
What is the difference between Op Area Safety and Point to Point Safety?
Op Area = Safety calculation of a select area, can safely fire from anywhere inside that area to anywhere inside the Target Selection Box
Point to Point = Safety calculation from a single Firing Point to a single Impact Grid
What is the Joint Publication that covers all different Fire Support platforms from all different branches of service in the US Military?
The JFIRE, ATP 3-09.32
The 3 Standard Sheafs that cannons can fire in are Converged, Parallel, and Open. What is the difference?
Converged = All cannons fire at the exact same spot
Parallel = Cannons fire in the same pattern as their displacement
Open = Impacts in line with each other, separated by one burst width
What is the preferred method of displacement for MLRS batteries?
Displacement by PLT
What are the elements of a Message to Observer IN ORDER?
Unit to Fire, Changes or Additions to the CFF, # of RNDS, Target Number
What is the difference between an Impact Area and the Useable Portion of the Impact Area?
Impact Area = Area established by Range Control where rounds are able to safely impact
Useable Portion of the Impact Area = Portion used for Rocket Safety, must be square or rectangular, perpendicular to the AoF, completely within the Impact Area
What is the HIMARS Resupply Vehicle? With attached trailer, how many pods can it Resupply?
M1084, with attached M1095 trailer it can carry 4x Launcher Pods
Terrain Gun Position Corrections (TGPCs) are values that are assigned to sections to enable the FDC to announce only ONE deflection and quadrant. How are they calculated?
1. Shoot a bump mission using all howitzers
2. Notate the difference in Deflection and Quadrant FROM the Base Piece TO the desired section
3. Record and announce as L/R for Deflection, Add or Drop for QE
How far away can a Launcher Hide Site be from its designated Firing Point?
Not closer than 20m, not further than 100m
Quick Smoke is a Special Munition that requires additional information from the Observer. We use the acronym LMDirT to remember this extra info, what does it stand for?
Length of smoke, Maneuver target line, Direction of wind, Time smoke needs to last for
Area F is the area to the rear of the launcher that is exposed to blast overpressure, fragments, and debris. What are the two parts that make it up, and how big are they?
- Launcher Danger Area = 400m each side, 400m to the rear
- Noise Hazard Area = Additional 300m from the LDA
What are the two options that BTRY CDRS have for employment of BTRY HQ / CP?
Consolidated CPs = All logistical and tactical operations happen at the same BOC
Dual CPs = Establishes a separate CP for logistical support called the LOC
When troubleshooting, what are the most common errors for Difference in Deflection VS Quadrant?
Deflection Errors = Gun Grids, TGT Grid, MET
Quadrant Errors = MVVs, Prop Temp, Ammo Info, MET
When conducting HIMARS Fire Missions, Section Chiefs have to make sure they are "balancing the pod". What does this mean?
Ensuring that rockets are fired in a way that allows weight to be evenly distributed across the pod to prevent the HIMARS from tipping over.
A Priority Target is a named TGT that has been designated as extremely important and must be fired extremely quickly. What is significant about Pri TGT in regards to MET?
After inputting new MET, the Priority TGT's data must be re-shot, re-verified, and called back down to the guns in order to make sure they are laid on the correct data.
When constructing Exclusion Area 1, what is the range for 1/1,000 Short Round Probability? What is the range for 1/10,000 Short Round Probability?
1/1,000 = 1,000m
1/10,000 = 2,500m
What are the six types of positions within an OP Area, usually selected by the PL?
Firing Point, Hide Site, Reload Point, Survey Control Point, PLT HQ, Ammo Holding Area
