Sample Questions
Question
1
In M32 misfire procedures, what should you do after the third misfire attempt?
Explanation:
After three misfires, you must open the cylinder and inspect the round. This step recognizes that continued misfires are most often due to a dud or a damaged cartridge, not a problem you can fix by hammering again or cycling the cylinder. Opening the cylinder lets you visually inspect the cartridge, confirm whether the primer didn't ignite, and remove or set aside a dud before attempting fire again. It’s a safety check to identify a faulty round rather than blindly continuing attempts, which could lead to a delayed ignition or other dangerous conditions. Other actions like recocking or advancing the cylinder without inspecting don’t address the underlying issue and could waste time or create unsafe situations; putting the weapon on safe is prudent, but the immediate correct action after a third misfire is to open and inspect the round.
Question
2
Which weight class does the 81mm mortar fall into?
Explanation:
Mortar weight class is defined by the combination of caliber and the level of mobility and crew required to operate it. An 81mm mortar sits in the medium category because its caliber is larger than the light mortars (such as 60mm) and provides more range and payload, but it isn’t as heavy or as vehicle-dependent as the larger heavy mortars (like 120mm). This means it’s still portable by a small infantry crew with standard support gear, suitable for standard rifle-company to platoon-level indirect fire. The other options don’t fit: a light mortar is typically 60mm or smaller, a heavy mortar is 120mm or larger, and an antitank launcher is a different weapon system altogether.
Question
3
Which unit is composed of multiple regiments and is typically commanded by a brigadier general?
Explanation:
In infantry formations, the level that brings together multiple regiments (or battalions) and is commanded by a brigadier general is a brigade. This size sits above a regiment (which is typically commanded by a colonel and may consist of several battalions) and below a division. A brigade is capable of independent operation and is the formation that aggregates several regiments or battalions under one commander. The other units—regiment/group, battalion/squadron, and company/battery—are progressively smaller and led by lower-ranking officers. Therefore, the unit described is a brigade.
Question
4
Which SAFESOC term refers to impediments that slow or stop movement?
Explanation:
Obstacles are impediments that slow or stop movement, whether they’re natural terrain features or deliberate man-made barriers. In SAFESOC planning, obstacles include things like minefields, barbed wire, destroyed structures, or rugged ground that block routes and force changes in maneuver. Their purpose is to slow, channel, or halt an enemy’s advance, and planners and engineers work to detect, mark, breach, or bypass them as part of maneuver. Avenues of approach describe potential enemy routes into the objective, not things that hinder movement. Entrenchment refers to fortified positions, not hindrances to movement. Camouflage/continuous actions deal with concealment and ongoing activity, not movement restrictions. So the term that best fits is obstacles.
Question
5
In LAAW misfire procedures, before attempting a third shot, which safety check is performed?
Explanation:
The main thing being tested is backblast safety. LAAW backblast can seriously injure anyone behind the launcher, so when a misfire occurs you don’t rush into another shot. You first verify the area behind the weapon is clear and that the backblast path is unobstructed. If people or obstacles are in the backblast zone, a third shot must be delayed until it’s safe. This check directly protects personnel and equipment from the dangerous blast that travels behind the launcher. Other options aren’t the immediate safety check needed before a third attempt. Opening the breech or ensuring the cradle status relate to loading, unloading, or handling the launcher, but the step required before firing again is to confirm the backblast area is clear.
