The disclosure of the order of 13 First Win II wheeled vehicles was announced by the Thai Army spokesman, Colonel Winthai Suvaree, to clarify to the media regarding the approval by the Thai Cabinet of the procurement of 34 VN1 8x8 IFV from NORINCO that the First Win is a MARP and is not in the same category as the VN1 which is an IFV.

Koolhiran explained the improvements made to the First Win 2 compared to the first generation of mine-resistant ambush-protected (MRAP) vehicles.

Excerpt

The most significant is an increase in armour protection. Ballistic protection of the hull has moved from STANAG 4569 Level 1 to 2, while mine blast protection offered by the V-shaped hull has moved from STANAG 4569 Level 2 to 3b.

This enhanced protection has been achieved without any increase in its 11t weight thanks to the use of new imported armour steel. That means there was no need for modifications to be made to the First Win 2’s Cummins ISB 300hp engine coupled to an Allison 2500 automatic transmission. Applique armour can be added to further increase hull protection.

A second major improvement on the First Win 2 is the integration of a digital backbone into the vehicle. As well as a command-and-control system, this backbone connects to an all-round thermal camera system for the driver and commander (up to 16 cameras) and a laser warning system connected to smoke grenade launchers.

Armament of First Win armoured vehicle

The First Win tactical vehicle features a remotely-operated turret system, armed with 0.5-calibre machine gun or 7.62mm light machine gun.

The Malaysian variant is outfitted with a 360°-rotating manual turret system with a ballistic protection hatch and a spring-loaded pintle mount to carry 7.62mm general-purpose machine gun or 12.7mm heavy machine gun. The 76mm grenade launchers on either side of the vehicle provide additional survivability.

Protection features

The armoured vehicle's cabin is armoured to the STANAG Level 2 ballistic protection, while its engine compartment is protected up to STANAG Level 1 standard.

"The First Win vehicles are operational with the Royal Thai Army and the Thai Ministry of Justice."

The monocoque hull offers blast protection and survivability up to STANAG 4569 Level 3b against the explosion of an 8kg TNT mine under the vehicle, and up to STANAG 4569 Level 4a against the blast of 10kg mine under any wheel.

Engine and driveline

A Cummins ISB engine, mounted at the front, provides high mobility to the vehicle. The engine generates an output power of 300hp at 2,850rpm and a torque of 475nm at 3,100rpm, and is coupled to an Allison 2500 automatic transmission system, which has six forward and one reverse gear. Power-to-weight ratio of the vehicle is 23hp/t.
