The Danish Army prepared a recommendation for modernisation of its fleet of M113A1 armoured personnel carriers (APCs) and in October 1995, the Danish Army announced its intent to modernise the current fleet of M113A1 APC´s. A subsequent request for quote (RFQ) for prototype test vehicles which followed, specified Danish operational requirements. Two competing teams participated in the prototype phase of the upgrade program: Marvin Land Systems (MLS) and a team composed of United Defense L.P. (UDLP - now owned by the US Carlyle Group) in conjunction with E. Falck Schmidt of Denmark.
MLS proposed two different upgrade packages: a "low end" MLS M113A2Plus, equipped with the 270hp powerpack, and a "high end" MLS M113A3Plus, equipped with the 350hp powerpack.
The UDLP/Falck team proposed a standard M113A3 and an M113A2 Mk 1.
A third team, the Flensburger Fahrzeugbau Gesellschaft (FFG), Germany, came later on proposing a third solution which were chosen.

The proposal consisted of a new and more powerful 6-cylinder, 10.6 liter turbo-charged diesel-engine (MTU 6V 183 TC22 EURO II) developing 300 hp with a ZF LSG 1000 transmission (6F2R), improved suspension, prepared for adding increased armour (URDAN type), external fuel-tanks, Diehl 513 tracks, new heater (Stewart-Warner, type 10560 M), new 200 AMP generator and improved steering- and brake system in order to make the APC´s more safe in traffic.
In addition, the engine fulfils the EURO 2 standard regarding emissions and noise levels and can be replaced in the field within an hour.
Gross Vehicle Weight (GVW) has been increased to 15.000 kg (33.000 lb.).

Initially 97 APC´s of the Danish Reaction Brigade went through this program. The modified APC has been designated "M113 G3 DK"
FFG has delivered a similar upgrade for the German Army.

In May 1999 it was decided that a total of 257 were to be upgraded.
Some 70 vehicles (77 kb) have been extended approx. 66 cm and have been added an extra road-wheel.
The first vehicles were scheduled to be delivered ultimo 2001, and the last by end of 2004.

In 2009 and 2010 the G3´s used in Afghanistan has been upgraded with belly protection, rubber tracks, adjustable seats and other features. This upgrade has been standardized and further vehicles has been upgraded in 2011 and 2012. The upgraded vehicles are designated G4 DK (109 kb).

Variants:
M113G3 DK, Platoon Vehicle (134 kb)
M113G3 DK Mine Roller (116 kb)
