3rd Carabiniers The 3rd Carabiniers ( Prince of Wales ' s Dragoon Guards ) was a cavalry regiment of the British Army . History . The regiment was formed in 1922 as part of a reduction in the army ' s cavalry by the amalgamation of the 3rd Dragoon Guards ( Prince of Wales ' s ) and The Carabiniers ( 6th Dragoon Guards ) , to form the 3rd / 6th Dragoon Guards . Both regiments were based in India at the time of their amalgamation ; the newly formed regiment departed in 1925 for Britain . It regained its carabinier association in 1928 when it was renamed the 3rd Carabiniers ( Prince of Wales ' s Dragoon Guards ) . In 1936 the 3rd Carabiniers was posted to Sialkot , India ; their first deployment of the 1930s . It began its mechanisation process in 1938 , changing its horses for armoured vehicles , and became part of the newly formed Royal Armoured Corps ( RAC ) the following year . Second World War . When the war began in September 1939 , the 3rd Carabiniers were still based in India . In 1941 , a cadre from the regiment was used to form the 25th Dragoons , which saw service in Burma ; it was disbanded in India in 1947 . The 3rd Carabiniers , itself , would serve solely in Asia after Japan ' s entry into the war in December 1941 . The regiment was initially based away from the frontline , guarding southern India from potential Japanese invasion . In 1943 , it absorbed the personnel of the recently disbanded 26th Hussars . Now equipped with the M3 Lee medium tank , the regiment was sent to North - East India with the 254th Indian Tank Brigade in December 1943 . They took part in the Battle of Imphal , which began in late March 1944 after the Japanese launched the U - Go offensive . On 20 March , around Tamu six of the regiment ' s tanks clashed with six Japanese Type 95 Ha - Go tanks , destroying five of them and capturing the other . Later , in the battle to retake Nunshigum Ridge , on 13 April , tanks from the regiment ' s ' B ' Squadron supported the 1 / 17th Dogras in fierce fighting that dislodged the Japanese defenders . The Nunshigum action later became the 3rd Carabiniers ' regimental anniversary . The regiment continued its involvement in the Imphal battle until the Allied victory at Kohima on 22 June 1944 ended the Japanese offensive . The 3rd Carabiniers , operating usually at squadron level or lower , took part in the successful advance deep into occupied Burma , taking part in ( among others ) an intense action at Kennedy Peak . Early 1945 saw the regiment engaged in fighting at Shwebo and Sagang ; it took part in the capture of Ava and Mandalay in March , and later around the Irrawaddy River . Post - World War II . After the war ' s official end in September , the regiment remained part of the British garrison in India up until the British withdrawal . The regiment ' s departure came in early 1947 when they embarked aboard the " Highland Princess " at Bombay , becoming the last cavalry regiment to leave India . The 3rd Carabiniers was posted to the British Army of the Rhine in West Germany in 1952 , based in Osnabrück remaining there until 1959 . After that , it moved to Catterick , England , but its stay there was short , as it joined the Strategic Reserve at Tidworth the following year . In 1961 the regiment deployed its ' C ' Squadron to Kuwait as part of a British force charged with deterring Iraq from fulfilling its threats to annex it . A return to West Germany came the following year , when it joined the 20th Armoured Brigade in Detmold . Having been armed with tanks since the early 1950s , the regiment was re - roled to a reconnaissance unit in 1967 , first operating the Ferret scout car . Deployments to the British military installations in Libya and Cyprus followed . The regiment in 1968 also had one squadron each in Sharjah and Aden . A brief posting to Münster , West Germany took place in 1969 before moving to Herford , West Germany . On 2 July 1971 , the regiment amalgamated with the Royal Scots Greys ( 2nd Dragoons ) , forming the Royal Scots Dragoon Guards ( Carabiniers and Greys ) . Battle honours . The 3rd Carabiniers possessed a total of 62 battle honour s , of which 49 were inherited from its predecessor units and were earned prior to the regiment ' s formation in 1922 . During the Second World War , the amalgamated regiment received 13 battle honours . The full list of battle honours held by the regiment are :
