In November 1961, the Battalion returned to Germany to become part of the 4th Guards Brigade, occupying the same barracks in Hubbelrath that they had left eight years earlier. After an enjoyable two years they returned Chelsea Barracks, London and two years later on to Elizabeth Barracks, Pirbright. In October 1966 the Battalion emplaned for Aden as part of 24th Infantry Brigade taking over Internal Security from the 1st Battalion Welsh Guards. Within a few days of arriving in Aden, they embarked on HMS Fearless to carry out a cordon and search operation in the East Aden Protecorate. This turned out to be a sucessful operation, resulting in the capture of a number of known dissidents, arms, ammunition and documents.

Duties in Aden comprised partly of up-country tours of North West Frontier style picqueting and keeping roads open at Habilayn and Dhala, as well as Battalion sized forays into the Djebel areas. In Little Aden the down-country tours consisted of active urban patrolling and checkpoints. The Battalion helped to load ships for the evacuation of stores. In addition Nos 1 and 3 Companies were hurriedly despatched in June 1967 to Mukalla in the East Aden Protectorate, when operations in the Hahdramout at Seyiun to rescue British Nationals took place.

The Battalion returned to Elizabeth Barracks, Pirbright in August 1967. From there it carried out Public Duties until it moved to Victoria Barracks, Windsor in September 1968. The time at Windsor was greatly saddened by the death in June 1969 on the Fifth Colonel of the Regiment, Field Marshal The Earl Alexander of Tunis KG. His body lay in state in Victoria barracks and it was from there that his funeral procession left for St George's Chapel with a Bearer party and Escort from the Battalion. The Battalion also provided the Guards of Honour outside the Chapel.

In November 1970 the Battalion moved to Hong Kong. Whilst there some it's duties were to patrol the Sin-Hong Kong border to prevent infiltration by the Chinese into Hong Kong. In December 1972 the Battalion returned to Caterham and in 1973 approximately 430 members of the Battalion carried out a six-month tour of duty to Belize, Central America. In June 1974 the Battalion found itself once again finding the Escort and Number Two Guard for the Queen's Birthday Parade followed in August of the same year converting for it's new role in Germany, moving to Münster in the December to join the 4th Guards Armoured Brigade as a mechanised Battalion for a three year tour.

The Battalion moved back to Victoria Barracks in November 1977 and almost immediately found itself taking part in Operation Burberry fighting fires in London during the Firemen's strike, using the Green Goddess fire engines. In February 1979, the Battalion embarked on a six month tour of Belize.
