Enschel Wehrtechnik UR-416 M Armoured Personnel Carrier

Development

The UR-416 was developed by Rheinstahl Maschinenbau (which became Thyssen Maschinenbau and today is known as Henschel Wehrtechnik GmbH) as a private venture, the first prototype being completed in 1965. Production commenced in 1969 and by the time production had been completed a total of 1,030 vehicles had been built, most for the export market. The UR-416 series is no longer being marketed and has been replaced by the TM-170 (4 x 4) vehicle covered in detail in the previous entry. The vehicle has been designed primarily for internal security operations but can also be used for a wide variety of other roles such as command and communications, reconnaissance and field workshop. The UR-416 is essentially the chassis of a Mercedes-Benz Unimog cross-country vehicle fitted with an armoured body. Spare automotive parts are identical to those used in the truck and are therefore available from commercial sources.

Description

The last production model of the UR-416 is called the UR-416 M. The modifications and improvements have been included in the following detailed description. The hull of the UR-416 M is of all-welded steel armour construction which protects the crew against small arms fire, shell splinters and anti-personnel mines. The driver is seated at the front of the vehicle on the left, just behind the engine, with the vehicle commander to his right. Both have a large bulletproof front and side window for improved visibility. Armoured flaps covering the commander's and driver's front windows are lowered by gas pressure, and side windows are protected by swivelling armoured flaps. Forward observation is maintained by two single periscopes in the forward part of the roof. The engine is coupled to a manual gearbox which has six forward and two reverse gears. For normal road use only the rear axle is engaged but for cross-country travel the front axle is also engaged and when travelling across very rough country the front and rear axle differential locks are engaged.
The eight fully equipped men are seated to the rear of the commander and driver, three down each side of the hull facing outwards and two at the back facing the rear. Each man has an individual seat which can be folded upwards. There are three doors, one in each side of the hull and one at the rear. The side doors are in two parts: the lower part folds downwards to form a step and the upper part is hinged on one side and folds flat onto the side of the hull. The rear door is a wide gas spring supported ramp allowing fast mounting and dismounting of the crew with the spare wheel and tyre mounted externally.
There are six firing ports altogether, two in the rear door, one in each of the side doors and a further two ports in the hull side. In addition, each sidewall has an observation block fitted with a spherical ball mount underneath.
In the roof of the UR-416 M, behind the commander and driver, is a circular single-piece hatch that opens to the rear and is secured on the roof. The basic model is normally armed with a 7.62 mm machine gun with a shield, which has an elevation of +75, a depression of -10 and a total traverse of 360. It can also be delivered with a horseshoe-shaped rail on which a 7.62 mm machine gun and shield with a traverse of 235 can be mounted. To the rear of this armament installation is a forward-opening single-piece hatch cover, normally with a single firing port which can be used when the hatch is locked vertical.

Forward of the commander's and driver's position are two side-mounted ventilators which draw in fresh air from the outside and pipe it to two channels which run down either side of the crew compartment. Each channel has six controlled air outlets which can be adjusted by the crew. The crew compartment also has handrails, lights and mountings for personnel equipment. A feature of the UR-416 M is that the armoured body can be removed and lifted from the chassis for major repairs and overhaul such as changing the engine. The lifting equipment consists of three jacks, one of which is fitted under each side of the hull and the third at the rear which acts as a pivot. The chassis can be driven away once the superstructure has been lifted. Optional equipment includes an automatic fire warning and extinguishing system, an independent heater, night vision periscopes, run-flat tyres, smoke dischargers (either turret- or hull-mounted) and an air conditioning system. A 5,000 kg capacity winch with 40 m of 12 mm diameter cable can also be fitted. This can either be driven by the PTO of the engine or an independent unit mounted on one half of the exit door.

Variants

Ambulance

Carrying eight sitting, or four sitting and two stretcher patients plus a crew of two.

Command and Communications

Fitted with additional communications equipment and map boards.

Internal Security

The internal security model can be fitted with an obstacle-clearing blade at the front of the hull. The lower half of the blade is made of welded steel with web stiffening, and the upper half consists of a pipe framework with a robust wire grille which gives the driver and commander forward observation. The height of the blade can be adjusted hydraulically from the driver's seat and it can also be removed for transport when it is usually stowed at the rear of the hull.
The vehicle can be fitted with the same turrets as the reconnaissance model but one cupola has been specifically developed for the internal security role. This cupola can be rotated through 360 and is infinitely lockable in any required position. At the front of the cupola above each other are two vision blocks with bulletproof glass and ball mounts. The cupola hatch opens to the rear and can be locked at 180. Two vision blocks with ball mounts and a further 10 vision blocks (in double rows) give improved observation. To the right of the two ball mounts is a flap which is opened to hold a tear gas nozzle. Tear gas mixture is provided from tanks which hold a maximum of 500 litres.

Reconnaissance

This could be fitted with most types of turret on the market.

Workshop

This has a full range of tools, work benches, a vice and cutting equipment, and an A-frame can be erected at the front of the hull to enable the vehicle to change engines and other components. When the A-frame is in use, two stabilisers are lowered at the front of the hull.
