The cherished dream of Sri Lankan cavalrymen to roll tanks on Sri Lankan battle fields came true withthe raising of 4 Armoured Regiment as the first the ever Tank Regiment. The Regiment on our soil. The Regiment was formally raised on 24 September 1991 at Rock House camp. Lt Col C S N B Muddannayake RWP psc chosen to be was hand picked to be the first Commanding Officer. The Regiment moved to Trincomalee on 10 October 1991 and occupied a part of the Clappenburg - Air Force Hangar Complex used by the Food Department as warehouses at China Bay.

They checked and handed over the equipments the same day, and commenced the first training course on 01 November 1991.


In late December 1991 the first tank troop was sea lifted to Palaly by LCM with Capt DT Gamage, the troop leader. Loading was done from the pier constructed at Clappenburgh after detail sea and land reconnaissance. This pier later became the permanent loading point for tanks. A notable development in the Regiment was the formation of the Light Aid Detachment with SLEME personnel with Capt W G C Gunarathne as the Officer Commanding.

A team of 15 x Army Officers and civilians from Czechlovakia arrived in late January 1992 to conduct a three months Advanced Tank Training Course. The course was conducted at Clappenburg with live firing at Villankulama. Simultaneously a group of 4 Officer and 40 other ranks left to Pakistan in early February 1992 for tank training.

a. Maj M P Peiris - OC A Squadron.
b. Maj B A Perera - OC B Squadron.
c. Capt A Ratnayake OC C Squadron.
d. CaptU A A Wimalaweera OC HQ Squadron.

A noteworthy event in April 1992 was a visit by the First Lady Madam Hema Premadasa to the Regiment on Sinhala New Year day. Service Commanders accompanied her.

A new dimension in the use of MBTs was unvlild when a T 55A MBT fired off a 70-ton barge for trial purposes on 05 May 1992 at Clappenburg. Targets were placed at Elephant Island 3500 m away were engaged successfully. Tankers elsewhere in the world would be amazed at the way tanks are employed in Sri Lanka. By this time, the entire Regiment was deployed in Jaffna Peninsula. Home base at Clappenburg was manned by Headquarter Squadron with Second in Command in location. Construction of Buildings and other infrastructure at Clappenburg continued under the supervision of 2IC Maj R M Jayasinghe. The base was gradually transformed into a beautiful military camp.

On 24 September 1992 the Regiment celebrated its first Anniversary at Clappenburg. A customary parade including a mini drive – past by 02 x MBTs (The only number available at Clappenburg), and an all Ranks lunch was held. The day’s events included the opening of renovated Officers Mess by the Regimental Commander Brig R De S Daluwatte. As the only tank Regiment in Sri Lanka, the Regiment had to participate in almost all operations, conducted during 1993. Tankers were on tracks throughout the year.

Due to scarcity of troops, ranks belonging to C Squadron were absorbed to A & B Squadrons, in February 1995. The Regiment continued training during lull periods in battle. Noteworthy accomplishment of the Regiment during Operation RIVIRESA and liberation of Jaffna Peninsula in 1995 was the resounding success achieved due to the shear firepower of the “Tankers”

In 1996, for better administration, Regimental Headquarters was moved from Trincomalee to Palaly. During the year the Regiment was committed on lot of operations. It the beginning of 1997, Tactical Headquarters with all three Sabre Squadrons were deployed at Elephant Pass with Regimental Headquarters in located Trincomalee.

It was a time the regiment needed a lot of spare parts to keep the fleet of 25 tanks operational. All tanks of A Squadron were off road due to shortage of major assemblies. Tank Troops were employed to protect the A 9 Main Supply Route from Tandikulam to Omantai.

By 01 January 2000, the Headquarter was shifted to Tandikulam with A Squadron. C Squadron was deployed in Mannar and Vavuniya. B Squadron remained in Elephant Pass. During this period the Commanding Officer planned a Squadron changeover. A Squadron was redeployed at Elephant pass to relieve B Squadron which has been deployed in the Jaffna peninsula from the beginning. The LTTE delayed the action by attacking the defences of Elephant pass on 25 March. By this time, the unit had only 24 Tanks and was waiting to receive another fleet of tanks and a load of much needed spares. On 04 of July the Commanding Officer visited the Czech Republic to inspect the tanks, which were prepared for dispatch to Sri Lanka. The Millennium Officers Mess get – together was held at Clappenburg with all past Commanding Officer including the “Father of the Regiment”, Brigadier C S N B Mudannayake RWP USP psc, and all serving Officers.

The Regiment with a mere fleet of 25 tanks and operating without vital spare parts, received a consignment of spare parts and a fleet of 36 new T 55 AM 2 MBTs. These MBTs were equipped with modernized Fire Control Systems. The first fleet of 11 x Tanks arrived at the Colombo harbour on 06 January 2001.

By end of August all MBTs of B Squadron, deployed in Vavuniya, were handed over to 3 SLAC. Withthis change D Squadron was designated B Squadron and three Squadrons were deployed in Jaffna peninsula with Tactical Headquarters.

Withthe declaration of a Unilateral Cease – Fire by the LTTE in 2002, all guns fell silent. The government too declared a Cease Fire and the Commanding Officer directed all squadrons to commence training. Subsequently all squadrons commenced troop and squadron training in their respective locations.

The first serious RPG casualties were suffered when two tanks were hit in the heavily built up areas of Tellippalai. They were repaired by the LAD and were back in action shortly.
