AMMO 49 — AMMUNITION & EXPLOSIVES EXAM 2026
VERIFIED QUESTIONS WITH CORRECT ANSWERS & EXPERT RATIONALE
1. What is the definition of an explosive?
A. A substance that produces heat and light when burned slowly
B. A chemical compound or mixture that reacts to produce gas, heat, and pressure
at a rapid rate
C. Any flammable liquid with a flash point below 140°F
D. A substance capable of sustaining combustion for more than 10 seconds
E. Any solid material that can be ignited by friction
Correct Answer: B. A chemical compound or mixture that reacts to
produce gas, heat, and pressure at a rapid rate
EXPERT RATIONALE: An explosive is defined as a substance or mixture of substances
that, upon initiation, undergoes a rapid chemical reaction producing large volumes of
gas, heat, and pressure — the fundamental characteristics of an explosive event.
,2. Which type of explosive is the most sensitive and is used to initiate the
explosion of less sensitive explosives?
A. Secondary explosive
B. Propellant
C. Primary explosive
D. Blasting agent
E. Bursting charge
Correct Answer: C. Primary explosive
EXPERT RATIONALE: Primary explosives are highly sensitive to heat, shock, friction, and
spark. They are used in primers and detonators to initiate the detonation of less
sensitive secondary explosives.
3. Which of the following is an example of a secondary explosive?
A. Lead azide
B. Mercury fulminate
C. TNT (Trinitrotoluene)
D. Lead styphnate
E. Diazodinitrophenol (DDNP)
Correct Answer: C. TNT (Trinitrotoluene)
EXPERT RATIONALE: TNT is a secondary explosive — it is relatively insensitive to heat,
shock, and friction and requires a primary explosive (detonator) to initiate detonation.
Lead azide, mercury fulminate, lead styphnate, and DDNP are all primary explosives.
4. What term describes the rapid decomposition of an explosive in which the
reaction front travels FASTER than the speed of sound in the material?
,A. Deflagration
B. Combustion
C. Detonation
D. Sublimation
E. Pyrolysis
Correct Answer: C. Detonation
EXPERT RATIONALE: Detonation is the explosive reaction in which the shock wave
travels through the explosive material faster than the speed of sound (supersonic). This
distinguishes it from deflagration, which is a subsonic burning process.
5. What is deflagration?
A. A supersonic explosive reaction that shatters surrounding material
B. A subsonic burning reaction that can transition to detonation under confinement
C. The complete failure of an explosive to function
D. A nuclear chain reaction
E. The slow thermal decomposition of an explosive over time
Correct Answer: B. A subsonic burning reaction that can transition to
detonation under confinement
EXPERT RATIONALE: Deflagration is a rapid combustion that propagates through an
explosive at subsonic speeds. Under confinement or with increased pressure,
deflagration can transition to detonation — a process called Deflagration to Detonation
Transition (DDT).
6. The term "sympathetic detonation" refers to which of the following?
A. The intentional detonation of unexploded ordnance by EOD
, B. Detonation of an explosive caused by the shock wave or detonation of a nearby
explosive
C. Simultaneous detonation of two charges placed at equal distances
D. A controlled detonation performed by trained demolition personnel
E. The chain detonation of linked explosive devices in a pre-planned sequence
Correct Answer: B. Detonation of an explosive caused by the shock wave
or detonation of a nearby explosive
EXPERT RATIONALE: Sympathetic detonation occurs when the detonation of one
explosive initiates the detonation of another nearby explosive through transmitted shock
waves. This is a primary consideration in quantity-distance planning and ammunition
storage requirements.
7. What does the term "TNT equivalent" represent?
A. The total nitrogen content of a given explosive compound
B. A measure of the energy released by an explosive compared to an equal weight
of TNT
C. The threshold temperature needed to detonate TNT in storage
D. The pressure exerted per square inch during a TNT detonation
E. A classification for all explosives with similar chemical compositions to TNT
Correct Answer: B. A measure of the energy released by an explosive
compared to an equal weight of TNT
EXPERT RATIONALE: TNT equivalent is a standard measure used to compare the energy
output of various explosives relative to TNT. It allows for normalized comparisons of
explosive power and is used in quantity-distance calculations.
8. Which factor does NOT directly affect the sensitivity of an explosive?
A. Temperature of the surrounding environment
