WOBC CVID EXAM 2026/2027 | COMBAT VEHICLE IDENTIFICATION PRACTICE
QUESTIONS
DOCUMENT OVERVIEW
• Comprehensive 200-question assessment covering modern and legacy Main
Battle Tanks (MBTs) including M1 Abrams, Challenger 2, Leclerc, Leopard 2, T-series
variants, and additional global armored platforms for systematic study and mastery
• Study method: Work through each section systematically, review detailed
rationales for missed questions, cross-reference visual characteristics, and use this
material for repeated practice to build rapid vehicle identification skills under exam
conditions
SECTION 1: M1 ABRAMS IDENTIFICATION
1) What is the primary defining characteristic of the M1 Abrams' turret
profile?
A) Heavily sloped front with a pronounced bustle extending to the rear
B) Sharp angular corners with a flat front face
C) Rounded turret with a small gun mantlet
D) Box-shaped design with external armor appliqués
E) Wedge-shaped front with an extremely tall profile
CORRECT ANSWER: A) Heavily sloped front with a pronounced bustle
extending to the rear
,Rationale: The M1 Abrams features a distinctive deeply sloped turret front that
deflects incoming rounds and a notable bustle extending backward, creating an
unmistakable profile. This bustle houses autoloader ammunition and is a key
identifier. The slope is more pronounced than most contemporaries, and the
overall turret silhouette is instantly recognizable when viewed from the side.
2) Which gun system is standard on the M1A2 Abrams?
A) 105mm rifled gun
B) 120mm smoothbore gun
C) 125mm smoothbore gun
D) 140mm smoothbore experimental gun
E) 155mm main gun
CORRECT ANSWER: B) 120mm smoothbore gun
Rationale: The M1A2 variant upgraded from the 105mm to the 120mm smoothbore
gun (Rheinmetall design). This upgrade significantly increased firepower. The
105mm gun is found on original M1 and M1A1 variants, while the 120mm became
standard from the M1A1 onward and continues on M1A2 models.
3) What is the distinctive feature of the M1 Abrams' ammunition storage
arrangement?
A) Horizontal drum magazine in the turret
B) Vertically loaded magazine on the gun breech
C) Autoloader system in the turret bustle with blow-out panels
D) Manual loading tray system on the hull side
E) External ammunition racks mounted on the rear deck
CORRECT ANSWER: C) Autoloader system in the turret bustle with blow-out
panels
Rationale: The M1 Abrams uses an automated ammunition handling system with a
40-round carousel magazine in the turret bustle. Critically, the design includes
,blow-out panels on the bustle roof that vent internal explosion pressure outward
rather than into the crew compartment, a safety innovation not found on earlier
tanks.
4) How many crew members does an M1 Abrams typically carry?
A) 3 personnel
B) 4 personnel
C) 5 personnel
D) 6 personnel
E) 7 personnel
CORRECT ANSWER: B) 4 personnel
Rationale: The M1 Abrams crew consists of the commander, gunner, loader, and
driver—four personnel total. This is standard across all M1 variants. Earlier tanks
like the Chieftain carried 4, but some other contemporary designs used 3-person
crews, making this a distinguishing characteristic.
5) What engine powers the M1 Abrams?
A) Diesel V-12 turbocharged engine
B) Diesel V-8 turbocharged engine
C) Gas turbine engine
D) Hybrid diesel-electric system
E) Supercharged petrol engine
CORRECT ANSWER: C) Gas turbine engine
Rationale: The M1 Abrams is powered by a 1,500 hp Avco AGT-1500 gas turbine
engine. This is unique among NATO's frontline MBTs; most competitors use diesel
engines. The turbine provides exceptional power-to-weight ratio and rapid
acceleration but consumes significantly more fuel than diesel alternatives, a known
operational drawback.
6) What is the maximum road speed of the M1 Abrams?
, A) 45 km/h
B) 50 km/h
C) 55 km/h
D) 65 km/h
E) 72 km/h
CORRECT ANSWER: D) 65 km/h
Rationale: The M1 Abrams achieves a maximum road speed of 65 km/h
(approximately 40 mph). This high speed is enabled by its powerful turbine engine
and relatively light weight compared to other MBTs. This speed advantage is
tactically significant for rapid deployment and repositioning.
7) Which armor protection system was introduced on the M1A1?
A) Composite ceramic armor
B) Depleted uranium armor inserts
C) Active explosive reactive armor (ERA)
D) Layered steel composite
E) Reactive spaced armor tiles
CORRECT ANSWER: B) Depleted uranium armor inserts
Rationale: The M1A1 variant introduced depleted uranium (DU) armor inserts in the
turret and hull, significantly increasing protection against APFSDS and shaped-
charge threats. This enhanced armor package is a key differentiator between M1
(original) and M1A1 versions. The DU provides both superior hardness and self-
sharpening properties.
8) What is distinctive about the M1 Abrams' gun mantlet design?
A) Oversized spherical mantlet extending from turret
B) Flat rectangular design with minimal protrusion
C) Angular design with sloped sides matching turret slope
