During the British Raj, the British Indian Army troops depended for their medical treatment entirely on their regimental hospitals. In October 1918, Station Hospitals were sanctioned for the Indian troops. The Indian Hospital Corps initially was divided into 10 Division Companies, which corresponded to the 10 existing Military Divisions in India and Burma. They were located at Peshawar, Rawalpindi, Lahore, Multan, Quetta, Mhow, Poona, Meerut, Lucknow, Secunderabad and Rangoon. The whole corps was re-organized on command basis five companies of the IHC were created in 1932. No 1 Company was at Rawalpindi, No 2 Company at Lucknow, No 3 Company at Poona, No 4 Company at Quetta and No 5 Company at Rangoon. The World War II was responsible for rapid developments. The idea of having a homogeneous corps by amalgamating Indian Medical Services, Indian Medical Department and Indian Hospital Corps gradually took shape and Indian Army Medical Corps came into being on 3 April 1943. The medical institutions of the IAMC were concentrated in the areas, which were to subsequently become Pakistan. The British Raj in India had left its legacies in the territory, which later became Pakistan. The bulk of the troops of the British Indian Army were recruited from the areas, which became Pakistan. The threats of the Russian empire and a fear of Afghans and Central Asians overrunning the Indian territory had made the British rulers wary of the northwestern borders across the Hindu Kush mountains. The army was deployed at large scale. Rawalpindi was the pivotal military base, from where they controlled the command, logistics and services provided to those troops. It was the Headquarters, Northern Command. Armed Forces Medical Services were one of the most organized and highly developed support services in the British Indian Army. The members of the medical profession served in the Indian Medical Services, with pride and dignity. The senior jobs in civil medical services were also reserved for the medical professionals of the army. The troops of British Indian Army were deployed over an extensive area. They were exposed to the tropical climate. They were present in the heights of Chitral in the north-west to Burma in the east. The major bulk of their health related problems were of tropical infections and parasitic infestation. The medical services were committed for the prevention and treatment of tropical diseases. Combined Military Hospital and Military Hospital were the largest and the most well-equipped hospitals in this area at that time.
