Overview
This comprehensive study guide provides 205 unique practice questions for Soldiers and Marines
preparing for a Joint Light Tactical Vehicle operator or maintainer course examination in
2026/2027. Every item is aligned to the JLTV operator technical manual (TM 9-2320-452-10), AR
750-1 Army Materiel Maintenance Policy (2 February 2023), DA PAM 750-8 (TAMMS), AR 385-10
(Army Safety Program), ATP 4-31 (Recovery and BDAR), and the federal safety, environmental, and
supply authorities that actually govern tactical vehicle operations. Each question includes a citation,
a written rationale, and a full distractor analysis explaining why every incorrect option fails.
A note on authority and program status: the JLTV is a joint U.S. Army and U.S. Marine Corps program, not a
credential issued by a certifying board; course examinations are administered by the unit or school conducting
the training. The correct operator manual is the TM 9-2320-452 series, not a TM 9-2320-XXX placeholder and
not the TM 9-2355-335 series, which covers the M-ATV. TB 43-0001 publications are Equipment Improvement
Report and Maintenance Digests, not JLTV maintenance manuals. Oshkosh Defense built the original JLTV and
JLTV A1; AM General won the JLTV A2 follow-on production contract in February 2023. Vehicles built to military
specification and sold directly to the armed forces are exempt from the Federal Motor Vehicle Safety Standards
under 49 CFR 571.7(c), and military tactical vehicles are the category exempted from Clean Air Act inspection
and maintenance requirements, so FMVSS and EPA emissions rules are treated here as exemptions rather than
as compliance requirements. On 1 May 2025 the Army announced it would cancel further JLTV procurement
under the Army Transformation Initiative; the Marine Corps has reaffirmed its commitment to the platform,
foreign military sales continue, and roughly 20,000 fielded vehicles still require trained operators and
maintainers.

Rationale: The JLTV was a joint Army and Marine Corps program intended to replace a portion of the HMMWV
fleet.
Distractor Analysis:
A is incorrect: "The U.S. Army and the U.S. Air Force" — violates CRS Report IF11729, Joint Light Tactical
Vehicle (JLTV) and would breach scope/safety vs correct practice.
B is incorrect: "The U.S. Navy and the U.S. Marine Corps" — violates CRS Report IF11729, Joint Light
Tactical Vehicle (JLTV) and would breach scope/safety vs correct practice.
C is incorrect: "The U.S. Army and the U.S. Coast Guard" — violates CRS Report IF11729, Joint Light Tactical

D. The Family of Medium Tactical Vehicles (FMTV)
Correct Answer: C. The High Mobility Multipurpose Wheeled Vehicle (HMMWV)
CRS Report IF11729
Rationale: The JLTV addresses the payload, protection, and performance gap the HMMWV could not close.
Distractor Analysis:
A is incorrect: "The M939 five-ton truck" — violates CRS Report IF11729 and would breach scope/safety vs
correct practice.
B is incorrect: "The Stryker family of vehicles" — violates CRS Report IF11729 and would breach
scope/safety vs correct practice.
