Which instrument is primarily used to measure the elevation angle of an artillery tube?
Clinometer
Barometer
Theodolite
Quadrant
A quadrant is specifically calibrated to measure the elevation angle of artillery tubes. Clinometers can measure slopes in general but a quadrant is the standard tool in artillery. Theodolites measure both horizontal and vertical angles in surveying.
What happens to a projectile's range when the elevation angle increases from 30 to 45 degrees, assuming all other factors remain constant?
Range remains the same
Range decreases
Range increases to maximum at 45°
Range increases beyond maximum
On level ground and in a vacuum-like model, the maximum range is achieved at a 45° elevation angle. Below 45° the range is shorter, and above 45° range decreases symmetrically. This principle underpins basic ballistic trajectory calculations.
What is the primary purpose of establishing a safety zone around an artillery firing position?
Ammunition storage area
Prevent friendly casualties
Establishing a communication hub
Concealment from enemy observation
A safety zone is designated to keep friendly personnel and equipment out of the area affected by firing hazards. It reduces the risk of injury from blast effects and fragmentation. Concealment and communication hubs are separate considerations.
Which device is commonly used for digital communication between a forward observer and fire direction center?
Wireless radio
Field telephone
Hand signal flag
Morse code key
Wireless radios provide secure, digital voice and data transmission between forward observers and the fire direction center. They offer range and flexibility under combat conditions. Hand signals and telephones are less secure and less adaptable to modern fire control networks.
Which terrain feature is most critical for line-of-sight targeting?
Soil type
Temperature
Elevation
Vegetation density
Elevation directly affects line-of-sight between the observer and the target or between sensors. Higher or lower terrain can block or enable direct observation. Vegetation and soil type are secondary considerations for concealment or stability.
In artillery range calculations, what factor does a ballistic coefficient account for?
Air density
Crew fatigue
Gunpowder composition
Projectile drag shape
The ballistic coefficient quantifies how an individual projectile's shape and mass affect aerodynamic drag. A higher coefficient indicates less deceleration in flight. It does not directly account for propellant or crew factors.
When adjusting charge increments to extend range, which step is essential?
Reduce powder temperature
Increase elevation by 5°
Change fuse timing
Calculate new propellant charge
Extending range by charge adjustment requires recalculation of the propellant charge to ensure safe pressure levels and correct muzzle velocity. Elevation changes alone might not meet the desired range. Fuse timing relates to detonation delay, not range extension.
Who is responsible for final approval of a fire mission in a typical artillery firing process?
Forward observer
Battery commander
Battalion commander
Fire direction center
The fire direction center (FDC) computes, coordinates, and ultimately approves the fire mission before sending firing orders to the guns. The battery commander oversees the unit, but the FDC handles technical calculations and approval. Forward observers provide targeting data.
What is the minimum safe distance, also known as 'danger close' for 155mm artillery in meters?
200m
1000m
600m
300m
For 155mm artillery, the established danger close distance is 600 meters when delivering fire near friendly troops. This distance accounts for fragmentation radius and error margins. Other calibers have different danger close distances.
Which communication procedure ensures accuracy when passing target coordinates?
Use slang terms
Use only map references
Send coordinates once
Repeat numbers back
A three-way procedure, in which the receiver repeats back the coordinate figures exactly, verifies accuracy and prevents transmission errors. Sending coordinates only once or using slang increases the risk of misinterpretation. Map references alone can be ambiguous.
A forward observer receives a shift of 200 meters right and 100 meters over. How should they report this correction?
Right 200, Over 100
Left 200, Down 100
Right 100, Over 200
Up 200, Left 100
Corrections are given as right/left and over/grid based on impact point to target. A 200 meter right, 100 meter over adjustment moves the fall of shot correctly to the target. Other combinations reverse directions incorrectly.
How does air temperature variation affect artillery range?
Higher temperature increases range
Lower temperature increases range
Temperature has no effect
Higher temperature reduces range
Higher temperatures reduce air density, resulting in lower aerodynamic drag and slightly longer projectile range. Lower temperatures increase density and drag, shortening range. Artillery meteorological data always includes temperature for this reason.
Which method is used to verify the accuracy of a predicted fire mission before live firing?
Conduct registration fire
Ask other units to observe
Visual inspection of barrel
Use inert training rounds
Registration fire involves firing a limited number of rounds and adjusting based on observed impact spots to confirm the ballistic solution. Inert rounds do not replicate propellant effects accurately. Observation alone cannot confirm internal ballistics.
What information does a meteorological message (MET message) provide for fire control?
Radio frequencies
Supply levels
Enemy positions
Weather data
A MET message includes temperature, pressure, humidity, wind speed, and wind direction data. These variables are critical in calculating accurate firing solutions to correct for environmental effects. It does not include tactical or logistical information.
Which adjustment accounts for deflection due to crosswind in a fire mission?
Charge increment
Elevation correction
Drift correction
Fuse timing
Drift correction compensates for lateral movement of the projectile caused by crosswinds and the Coriolis effect. Elevation corrections adjust range, and fuse timing controls detonation, not deflection. Charge increments affect velocity and range only.
When refining a fire plan with reconnaissance data indicating target movement, what is the first action?
Update target coordinates
Withdraw observer
Change ammunition type
Immediately fire
Reconnaissance data that a target has moved requires updating the target's coordinates before any firing can proceed. Firing without updated coordinates risks missing the target or causing collateral damage. Ammunition changes follow once the new location is confirmed.
In joint fire support, what deconfliction measure assigns separated airspace for artillery and aviation?
Fire support coordination line
No-fire area
Air corridor
Restricted firing zone
An air corridor designates specific airspace for aircraft to operate safely above artillery effects. This prevents conflicts between rounds in flight and aerial platforms. Other measures restrict ground or firing activities rather than specifically separating air traffic.
Which advanced sensor data is most useful for adjusting fire against moving armored targets?
Infrared target locator
Thermal imaging
Ground-moving target indicator radar
Visual binoculars
Ground-moving target indicator (GMTI) radar can track and report speed and direction of moving armored targets in real time. Thermal imaging and infrared locators detect heat signatures but do not provide continuous movement vectors. Binoculars rely on clear line-of-sight and cannot quantify movement.
What ballistic model parameter is adjusted to compensate for high-altitude temperature differences?
Muzzle velocity
Atmospheric correction factor
Instantaneous center
Charge temperature coefficient
The atmospheric correction factor accounts for changes in air density and pressure at different altitudes and temperatures. This parameter modifies the ballistic solution to maintain accuracy. Muzzle velocity is measured but not the direct compensation parameter for atmospheric variation.
During a registration procedure, which pattern is commonly used to align fire for precision?
Ladder
Butterfly
Grid
Circular
The ladder registration pattern involves firing multiple rounds at successively increasing elevations to bracket the target range. This creates a range ladder that is then used to interpolate precise firing data. Other patterns are not standard for artillery registration.
