The incendiary composition of the 20 millimeter armor-piercing incendiary (API) round is initiated by impact. This means that when the round hits its target, the impact causes a reaction in the incendiary composition, leading to the release of heat and fire. The other options, such as inertia forces, fuze functioning, and friction during firing, may play a role in the overall functioning of the round, but they do not directly initiate the incendiary reaction.

The rotating band is a component of a 20 millimeter projectile that enables spin and stabilization in flight. As the projectile is fired, the rotating band engages with the rifling in the barrel, causing the projectile to spin rapidly. This spin helps to stabilize the projectile's flight, improving accuracy and increasing its range. The rotating band also provides a gas seal, preventing propellant gases from escaping and ensuring that the projectile achieves maximum velocity. Overall, the rotating band plays a crucial role in the performance of the 20 millimeter projectile during flight.

Hygroscopicity refers to the property of an explosive to absorb moisture. This means that the explosive has the ability to attract and retain water molecules from its surroundings. This property is important because moisture can affect the stability and performance of the explosive. Moisture-absorbing explosives are more prone to degradation and can become less effective over time. Therefore, understanding the hygroscopicity of an explosive is crucial in ensuring its reliability and safety.

The requirement for military explosives is that the raw materials must be cheap. This means that the cost of acquiring the raw materials should be low, allowing for the production of explosives in large quantities without putting a strain on the military budget. By using cheap raw materials, the military can ensure that they have an adequate supply of explosives to support their operations.

The primary reason the AN-MK13 Mod 0 signal can be handheld while burning is to allow a downed pilot to hold the flare while treading water. This suggests that the flare is designed to be easily held and operated by someone in water, indicating that it is waterproof and buoyant. This would enable a pilot who has ejected into water to easily signal for help without having to let go of the flare or risk dropping it.

The correct answer is 13,000. This is because the high fragmentation (HF) PGU-45/B projectile is designed to produce a large number of fragments upon detonation. The high fragmentation capability of the projectile allows it to break apart into numerous smaller pieces, resulting in a higher number of fragments. Therefore, it is expected that the projectile will produce approximately 13,000 fragments.

The correct answer is 15 feet. The factory set height of burst (HOB) for the FMU-160/B fuze is 15 feet. This means that the fuze is designed to detonate the explosive payload when it reaches a height of 15 feet above the target. This height is optimized for maximum lethality, as it allows the explosive to disperse and cause damage over a wider area.

The approximate length of a complete 105 millimeter round is 31 inches. This is because the length of the round is not given in millimeters, but in inches. Therefore, we need to convert the given length of 105 millimeters into inches. 105 millimeters is approximately equal to 4.13 inches. Hence, the correct answer is 31 inches.

The SD-206 infrared flare (Smokey Devil) provides smoke to simulate a flare for training purposes. This means that it is designed to emit smoke rather than heat, making it suitable for training exercises where the goal is to simulate the presence of a flare without the risk of causing a fire or generating excessive heat. The option stating that it provides less heat than the M206 flare is incorrect, as the SD-206 does not provide heat at all. The option mentioning more flexibility due to its smaller size and more heat than the M206 flare are also incorrect as they do not align with the purpose of the SD-206 flare.

To achieve an airburst with a general-purpose bomb, a time action high-explosive (HE) train is used. This means that the bomb is equipped with a timer that determines when the explosion will occur after the bomb is dropped. By setting the timer to the desired delay, the bomb can be detonated in mid-air, creating an airburst effect. This technique is often used to maximize the blast radius and damage potential of the bomb, especially in situations where ground impact may not be as effective.

The main types of fuze actions are impact, time, and proximity. Proximity fuzes are designed to detonate when they come within a certain distance of the target. This type of fuze is commonly used in air defense systems, where it can detect and explode near incoming enemy aircraft or missiles. Proximity fuzes rely on various technologies such as radar or infrared sensors to determine the distance to the target and initiate the detonation at the right moment. This allows for a higher probability of hitting the target and causing damage even if the projectile itself doesn't directly impact it.

The correct answer is that the projectile is non-separable and the total cartridge is gold in color. This means that the projectile cannot be separated from the cartridge, and the entire cartridge is painted gold. This is a distinguishing feature that sets it apart from other 25 mm rounds. The other options, such as being painted blue or being hollow and lighter, are not mentioned as characteristics of a 25 mm dummy cartridge.

Electric squibs (propellant-actuated devices) are similar to blasting caps. Both electric squibs and blasting caps are explosive devices that are used to initiate or trigger a larger explosion or combustion process. They are typically used in industries such as mining, demolition, and pyrotechnics. Electric squibs and blasting caps are designed to be activated through an electrical current, which causes a small explosion or ignition that sets off the main explosive charge. This similarity in function and activation method makes blasting caps the most appropriate comparison to electric squibs.

Deflagration is the correct answer because it refers to the tendency of a substance to burn rapidly and produce a sparkling combustion. It is a type of combustion that occurs at a subsonic speed and is characterized by a flame front that moves through the substance. This process is different from detonation, which involves a supersonic speed and a shock wave. Disposition refers to a person's inherent qualities or tendencies, while decomposition refers to the breakdown of a substance into simpler components.

A shaped charge is designed to produce an explosive penetration of a solid target. It is commonly used in military applications, such as anti-tank warfare, where it can effectively penetrate armored vehicles or fortifications. The charge is shaped in a way that focuses the explosive energy into a narrow jet, which can then penetrate the target with a high velocity. This makes it a powerful tool for demolishing structures, breaching barriers, or disabling enemy vehicles.

The correct answer is primer, bullet, and propellant. A small-arms cartridge consists of these three components. The primer is a small explosive charge that ignites the propellant when struck by the firing pin. The propellant is a chemical substance that burns rapidly, creating high-pressure gas to propel the bullet out of the cartridge case and down the barrel. The bullet is the projectile that is fired from the firearm.

White phosphorus is the correct answer for the filler of the M34 smoke grenade. White phosphorus is a highly reactive substance that ignites upon contact with air and produces thick white smoke. It is commonly used in smoke grenades to create a smokescreen for military operations or to signal locations. Adamsite and silica aerogel are not commonly used as fillers for smoke grenades, while chloroacetophenone is a tear gas agent and magnesium oxide is a fire retardant, making them unsuitable for smoke grenade fillers.
