Land Rover Tangi
Large plates of ballistic steel were bolted to the sides of the vehicle, which wrapped around the rear pillar and met with an armoured double door.
Both of these doors and the side plates were fitted with sliding pistol ports, allowing the officers inside to return fire in the event of an ambush.
For the protection of the driver and the front seat passenger, the windscreen and side windows were replaced with thick sheets of bulletproof glass, along with armour-plated doors.
However, due to the Simba's advanced and purpose built nature it was very slow to produce and the Hotspur Land Rovers were beginning to wear out, so a solution was needed to quickly get more armoured police vehicles on the streets.
The vehicles' headlights were initially protected from damage by transparent polycarbonate shields, but these were quickly found to be less durable than the original metal grilles of the Hotspur and were replaced.
At the front and rear of the roof each of the Tangis were fitted with a remotely controlled spotlight and a rotating blue warning light, all protected by expanded metal grilles.
The crew of the Land Rover were saved from serious injury as they had packed riot shields using ropes above their heads forming a second skin.
Similar IEDs were fitted with small drogues on the rear, so they could be thrown horizontally to strike the side of a Tangi thus circumventing the additional roof armour.
The RUC responded to this with a similar measure to the Dawson roof, fitting a plate of ballistic steel several inches from the hull to detonate the bomb before it struck the main armoured body.
In this final form, with the Dawson roof and hardened side armour, the Tangi is seen on the streets of Northern Ireland today.
[3] Since the Good Friday Agreement, the vehicles are largely used for crowd control, though some are still used for patrol purposes in areas where Dissident Paramilitaries still operate.
More than half of the former RUC (now PSNI) fleet of 450 armoured Land Rovers were decommissioned under the terms of the Good Friday Agreement.
It features a third driven axle to provide a 6x6 configuration and is capable of carrying a crew of two plus ten fully equipped soldiers over rugged terrain.
