The Rejimen Askar Wataniah is the reserve component of the Malaysian Army. An equivalent formation in the British Army would be the Territorial Army.
The Regiment infantry unit is divided into 2 series; the 300 series and the 500 series. The 300 series consist of 5 infantry battalions with mobilized reservists for full time duty. They are mostly posted at northern border check-points. The 500 series are reserve volunteers units, based in major towns and cities throughout the whole country. In all, there are about sixteen Regiments of the 500 series.
Volunteer Units In Malaya
In 1861, the Penang Volunteers were formed as a volunteer army unit of the Straits Settlement. Similar units were formed in Singapore and in the other Malay States.
In 1902, the Federated Malay States formed the Malay State Volunteer Rifles (MSVR) volunteer force. The Unfederated Malay States also formed their own volunteer units. With further expansion, the formations were then known as the Federated Malay States Volunteer Force (FMSVF), Unfederated Malay States Volunteer Force (UFMSVF) and the Straits Settlement Volunteer Force (SSVF). With the outbreak of the Second World War, the volunteer units were mobilised and fought alongside the regular British, Indian and Australian Armies in the defence of Malaya and Fortress Singapore.
World War II
During World War II, the Chinese dominated Malayan people’s Anti-Japanese Army undertook guerrilla war against the Japanese Occupation of Malaya. Even though the Malays have fought bravely alongside the British Forces that were eventually defeated in Singapore (February 1942), the British felt it imperative to involve Malays in resistance against the Japanese. During the Japanese Occupation, a number of local Malays formed resistance groups and carried out guerrilla warfare on the Japanese. Resistance units in Pahang were called WATANIAH, derived from the Turkish word VATAN. The Wataniah was led by Yeop Mahidin Bin Mohamed Shafiff (known as the Father of Wataniah). Force 136 of the Special Operations Executive was amongst the British formations that supported the Malayan resistance including the Wataniah movement against the Japanese Occupation.
After the war, the volunteer units were reformed. With the start of the Malayan Emergency, the Home Guard was raised and tasked with local static defence, thus releasing regular British, Commonwealth and Malayan units for combat operations against the Communist Terrorists. In 1958, with the security situation under control and the threat from the Communist Terrorists diminished, the Home Guard was disbanded.
However, many of the members of the Home Guard wished to continue their voluntary service, and the Federation Government agreed to the formation of the Territorial Army with the passing of the Territorial Army Ordinance 1958. The Askar Wataniah was formed on 1 June 1958.
The 500 series is tasked with the same mission as the combat infantry battalions of the Royal Malay Regiment and the Royal Ranger Regiment. There are currently 16 Wataniah Regiments, each comprising 3 (nominal) infantry battalions.

PASUKAN LATIHAN PEGAWAI SIMPANAN (PALAPES)
PALAPES units (Reserve Officers Training Units - ROTU) are formed at 12 universities and institutes of higher education to facilitate the recruitment of graduate officers.
Following the Confrontation, the Reserve unit was formed on 3 April 1965 as the 1st Infantry Battalion, Askar Wataniah (University Malaya) , mustered from amongst undergraduates and staff of Universiti Malaya. Initially 30 undergraduates from various faculties volunteered and underwent basic training during their semester breaks at the Recruit Training Camp at Kem Latihan Seputih, Batu Gajah, Perak. The majority of the recruits had prior experience in the Army and Police Cadets and many were former students of the Maktab Tentera Diraja (Royal Military College).
The aftermath of the 13 May 1969 riots saw the expansion of the Askar Wataniah unit to other universities with A Company formed in di Institut Teknologi MARA, B Company formed in Universiti Pertanian Malaysian (UPM) (now called Universiti Putra Malaysia) and C Company formed at Universiti Kebangsaan Malaysia while the unit at Universiti Malaya took on the role of battalion HQ.
On 18 December 1978, the Brigadier General Dato’ Abdul As Ismail, the Director of Askar Wataniah discussed the formation of the Reserve Officers Training Units with the university Vice Chancellors and the Director of ITM. Pursuant to the meeting, the Armed Forces Council approved the formation of the Reserve Officer Training Unit ROTU at Malaysian local universities to attract Reserve Officers from amongst staff and undergraduates of the various universities. ROTU is currently known as Pasukan Latihan Pegawai Simpanan (PALAPES).
There are currently 12 Malaysian public universities and institutions of higher education hosting PALAPES units. Units are formed at Universiti Malaya (PALAPES UM), Universiti Teknologi Malaysia, Universiti Kebangsaan Malaysia, Universiti Sains Malaysia, Universiti Putra Malaysia, Universiti Utara Malaysia, Universiti Malaysia Sarawak, Universiti Malaysia Sabah, Universiti Teknologi MARA, Universiti Tun Hussein Onn Malaysia, Universiti Pendidikan Sultan Idris and Kolej Universiti Kejuruteraan Utara Malaysia.
