Study Guide & Cheat Sheet with Verified Doctrinal Citations,
Full Rationales, and Distractor Analysis for Every Item
205 VERIFIED Q&As Randomized Choice Order Updated for 2026/2027 Full Rationales
Overview
This comprehensive study guide provides 205 unique practice questions for Marines preparing for
a Joint Light Tactical Vehicle operator course examination in 2026/2027. Every item is aligned to
the JLTV operator technical manual (TM 9-2320-452-10), MCO 4790.25 (Ground Equipment
Maintenance Program), MCO 4790.2 (Field-Level Maintenance Management Policy), TM 4700-15/1
(equipment records and forms), MCO 5100.19F (DRIVESAFE), MCO 5100.29C (Marine Corps Safety
Management System), and the federal safety 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 sourcing: a JLTV operator course examination is administered by the unit or formal
school conducting the training, not by a certifying board and not by a vehicle manufacturer. Within the Marine
Corps, Training and Education Command owns training standards while Marine Corps Systems Command and
Program Executive Officer Land Systems manage materiel; NAVSEA and NAVAIR manage ship and aviation
systems and are not JLTV authorities. Ground equipment maintenance is governed by the MCO 4790 series, not
by MCO 11200, and records and forms are governed by TM 4700-15/1. Marine Corps safety authority splits
between MCO 5100.19F, the traffic safety program known as DRIVESAFE, and MCO 5100.29C, the Marine Corps
Safety Management System, which is the source of risk management policy. The JLTV operator manual is the TM
9-2320-452 series; the TM 9-2355-335 series covers the M-ATV. The JLTV is a land tactical vehicle with a limited
fording capability, not an amphibious vehicle. Oshkosh Defense built the JLTV and JLTV A1, and AM General won
the JLTV A2 follow-on contract in February 2023. The Army announced the end of its own JLTV procurement on 1
May 2025, while the Marine Corps has reaffirmed its commitment to replacing its entire Humvee fleet with the
JLTV.
