Launch order for Carl-Gustaf M4
Terrex 2 muscles up
Saab has received the first order for
the new Carl-Gustaf M4 84mm recoil-
less rifle from the Slovak Republic, with
deliveries due in 2016.
Two other undisclosed countries
have acquired small quantities of the
Carl-Gustaf M4 for evaluation/qualifica-
Compatible with the range of 84mm
ammunition natures, the M4 (at less
than 7kg) is 3kg lighter and at less than
1,000mm in overall length is 60mm
shorter than the M3 model. The weight
savings in the M4 have been realised
largely through the adoption of a titani-
um barrel liner, modification of the car-
bon fibre outer casing and a redesigned
The M4 also features an integrated
electronic shot counter that automatical-
ly counts every full calibre round that is
fired through the weapon, enabling end
users to keep track of wear and replace
it before end of life-of-type is reached.
Unlike previous versions, the M4 can be
carried when loaded, enabling faster re-
action times for the gunner.

up’ in the Oct 2014 issue of DTR.

AUSTRALIA’S GLOBAL LOGISTICS SOLUTION SINCE 1976
ABOVE: Slovakia is the first customer for
the Carl-Gustaf M4 84mm recoilless rifle.
In response to growing customer de-
mand for increased protection and pay-
load, Singapore Technologies Kinetics
(STK) has released its Terrex 2 wheeled
armoured fighting vehicle.
Spoken of for some time in reference
to the US Marine Corp’s Amphibious
Combat Vehicle Phase 1 Increment 1
program and more recently Australia’s
Land 400 Combat Reconnaissance Ve-
hicle project, the Terrex 2 builds upon
the foundation laid by the original 24
tonne Terrex 8x8.
Featuring a redesigned, first-in-class
‘ V-over-V ’ twin-skin hull to improve pro-
tection against mine and improvised ex-
plosive device blasts, while maximising
crew space and maintaining payload,
DTR understands Terrex 2 possesses
greater protection against both blast
and kinetic threats.
The hull of Terrex 2 is also shaped
and optimised to support an amphibious
capability, where the in-water propulsion
system enables swim speeds of 6 knots
and the ability to navigate Sea State 4
conditions. Tests of earlier Terrex ver-
sions have proven its ability to come
ashore and exit the beach through the
To retain high mobility on land, Terrex
2 is powered by a 6-cylinder Caterpillar
C9.3 525-600hp diesel engine coupled
to an Allison 4500SP 6-speed auto-
matic transmission. All-wheel steering
aids manoeuvrability in difficult or re-
Integrating smart vetronics solutions
such as customisable driver touch-
screen dashboard displays, a day/night
camera surveillance system, closed
hatch driving system and vehicle naviga-
tion, the Terrex 2 delivers high situational
awareness for the crew and occupants
even when operating closed-down.
The Terrex 2 in the armoured per-
sonnel carrier configuration has a
crew of two (driver and commander)
and blast-attenuating seating for 12
troops, with space for mission loads as
required. The other three principle var-
iants are command post, engineer and
Armament options for the Terrex 2
include remote weapon systems for a
7.62mm medium machine gun, 12.7mm
heavy machine gun or 40mm automatic
grenade launcher mounted on the hull
roof. Turreted weapon systems for me-
dium-calibre cannon (25-40mm) can
also be fitted.
