Army Medical Corps (India)
The Indian Army Medical Corps is a specialist corps in the Indian Army which primarily provides medical services to all Army personnel, serving and veterans, along with their families. Early history
Very little is known of the medical organisations that existed in the Indian armies in ancient times. However, Kautilya's Arthashastra shows that during battles, physicians with surgical instruments (Shastra, medicines and drugs in their hands besides women with prepared food and beverages) stood behind the fighting men. Similarly, from the Sushrüt Samhitā, it is seen that a physician fully equipped with medicines would live in a camp not far from the royal pavilion and would treat those wounded by arrows or swords. Physicians in the King's service adopted certain measures to protect the ruler from secret poisoning. Physicians well versed in the technical sciences and other allied branches of study was held in high esteem by all. Later British Period
The Army Medical Corps came into existence as a homogeneous corps of officers and men on the pattern of the Royal Army Medical Corps on 3 Apr 1943 by the amalgamation of the Indian Medical Service, the Indian Medical Department and the Indian Hospital & Nursing Corps. The Corps was formed as a wartime necessity for attracting suitably qualified men for service in a rapidly expanding army. Indian Medical Service 

The history of the Indian Medical Service (IMS) dates back to 1612 when, on the formation of the East India Company, the Company appointed John Woodall as their first Surgeon General. Under him, medical Corps officers (mainly civilians) were recruited more or less on individual contracts. The company expanded activities in various part of the country 
which necessitated the formation and maintenance of regular bodies of troops in India. As a consequence, they commenced employing military surgeons from 1745 onwards. It was not until 1764 that these surgeons were made into regular establishment of the company's armies. Thus the Bengal Medical Service was formed in 1764, the Madras Medical Service in 1767 and the Bombay Medical Service in 1779 for the three Presidency Armies of Bengal, Madras and Bombay. The three medical services were combined into the Indian Medical Services (IMS) in Apr 1886 under a Surgeon General to the Government of India. The designation was later changed into the Director General, Indian Medical Service. In 1913, the appointment was designated as the Director of Medical Services in India. Until the First World War the IMS was predominantly civil in character, but gradually from 1912 onwards those employed in civil duties became less and less in number. Indianisation of this service commenced from 1915 onwards. Sarjoo Coomar Goodeve Chauckerbutty was the first Indian to enter the service as Assistant Surgeon on 24 Jan 1855. Until Burma was separated in 1935, the IMS was catering for the civil and military needs of Burma also. During this period, the IMS was assisted by the members of the Indian Medical Department (IMD) and Indian Hospital Corps (IHC). The idea of re-organising the medical services into a separate Medical Corps exclusively for the Defence Services was first conceived in 1939 with the out break of World War II and with the formation of Indian Army Medical Corps on 3 April 1943, the extinction of the IMS as such was merely a matter of time. On 14 Aug 1947 the service was finally wound up. Indian Medical Department 
The history of the Indian Medical Department (IMD) dates back to 19th century. Initially starting as compounders and dressers in the three Presidency Medical Services they became Sub Surgeons and later on as Indian Medical Assistants in Indian Regiments. In 1868, they were redesignated as Hospital Assistants. In 1900, the Senior Hospital Assistants were granted the rank of Viceroy's Commissioned Officers and in 1910 the designation was finally changed to Sub Assistant Surgeons of IMD. Army Medical Corps (AMC) were primarily for work with the Indian troops. Indian Hospital Corps 
The Indian Hospital Corps was formed on 1 June 1920 by combining the Army Hospital Corps and Army Bearer Corps and the subordinate personnel of Indian Station Hospitals, comprising persons of categories then considered necessary for hospitals, field ambulances and other medical units. Army Hospital Corps 
In the days of the East India Company there were no regular formations or units charged with the task of looking after the health of troops. In 1881 the British Regimental Hospitals gave way to British Station Hospitals and they needed subordinate persons. So in 1881, the Army Hospital Native Corps was formed of menials of the disbanded British Regimental Hospitals, Compounders, dressers, ward coolies, barbers, shop coolies, cooks, bhistis and sweepers and were designated as, Hospital Attendants. With the abolition of the Presidency Armies by the Government and the evolution of the Army into 10 Divisions, the Army Hospital Native Corps was re-organised into 10 Companies as Army Hospital Corps. Army Bearer Corps 
It was not until 1901 that the necessity for a proper corps of bearers was accepted by the Government and in this year, Dooly Bearers and Kahars were enlisted in the newly formed Army Bearer Corps, which came under the Medical Department. The Army Hospital Corps persons did the menial service in British Station Hospitals and the Army Bearer Corps provided persons for the carriage of the sick and wounded. In 1903, the Army Bearer Corps was re-organised into 10 Division Companies and the duties of these Companies in war were to carry stretchers and doolies, and in peace for general work in hospital. Station Hospitals 

Indian troops had no station hospital facilities until 1918, and had to depend entirely on their regimental hospitals. In October 1918, Station Hospitals for Indian troops were sanctioned. Ward orderlies and followers came from Army Hospital Corps and bearers were provided by the Army Bearer Corps. The IHC initially was divided into 10 Division Companies corresponding to the 10 existing Military Divisions in India and Burma and they were located at Peshwar, Rawalpindi, Lahore, Quetta, Mhow, Pune , Meerut, Lucknow, Secunderabad and Rangoon. The whole corps was re-organised on command basis during the year 1929-32 and thus there were five companies of the IHC in 1932, No 1 Company at Rawalpindi, No 2 Company at Lucknow, No 3 Company at Poona. No 4 Company at Quetta and No 5 Company at Rangoon. On separation of Burma in 1935, No 5 Company of IHC was formed as Burma Hospital Corps and this left four companies of IHC. World War II was responsible for rapid developments. The idea of having a homogeneous corps by amalgamating IMS, IMD gradually took shape and Indian Army Medical Corps (IAMC) came into being on 03 Apr 1943. On the formation of the IAMC, the IHC HQs at Poona became the Administrative Headquarters of the IAMC in May 1943. After Independence of the country, the Corps has made a steady progress. The men enjoy combatant status. The post of Director General Armed Forces Medical Services was created in 1949 as coordinating head of the medical services of the Army, Navy and Air Force. Combat operations and decorations 

The Indian Army Medical Corps has seen combat and active operations in all operations and wars the Indian Army was involved, as part of combat formations or as hospitals apart from providing life-saving services in tertiary/referral hospitals around the country. Capt John Alexander Sinton of the Indian Medical Service was awarded the Victoria Cross during world war one in Orah Ruins, Mesopotamia while serving with a Dogra battalion (presently a mechanized infantry battalion). 60 Parachute Field Ambulance was the first medical unit to be raised for airborne operations and to provide medical cover to 50 Indian Parachute Brigade in 1941, and was followed by 60 and 7 Parachute Field Ambulances, when the formation was increased to divisional strength. The unit under Lt Col Davis saw action in Sangshak during world war two where it, along with the rest of the depleted-strength parachute brigade was virtually wiped out, but it gave XIV Army enough time to prepare Manipur and Imphal plains for defence. The unit, along with the medical officers of the two para battalions earned several gallantry awards. Captain S Gopalakrishnan of the Indian Army Medical Corps, attached to 3rd Battalion, 5th Gorkha Rifles, was awarded the Military Cross on November 1944. Between March 22 and March 26th, while the battalion was pinned down by Japanese troops and snipers on Mile 98.4 on the Tiddim Road, Capt Gopalakrishnan worked round the clock for four days providing medical assistance and relief to the wounded. He ended up saving nearly a hundred lives according to the Citation. He later retired as a Brigadier in the Indian Army. Also of interest would be that the first Indian paratrooper was a medical officer, Lt (later Col) AG Rangaraj of 152 Indian Parachute Battalion. He later commanded 60 Indian Parachute Field Ambulance in Korea and was awarded Mahavir Chakra, the second highest gallantry award. Major Laishram Jyotin Singh awarded Ashok Chakra, highest peacetime gallantary award on 26 January 2011. Laishram Singh was born in 1972 in Manipur, India. He was commissioned in the Army Medical Corps in 2003, and was posted with the Indian Embassy in Kabul in 2010. Just thirteen days after his posting, a suicide bomber attacked the guarded residential compound where he was staying. [3] Major Singh confronted the terrorist unarmed and forced him to detonate his vest, which resulted in his death. He was awarded the Ashok Chakra "For his act of exemplary courage, grit, selflessness and valour in the face of a terrorist attack, resulting in his sacrifice and saving 10 of his colleagues.
