Traditionally, the army was a predominantly Punjabi force. In British India, three districts: Campbellpur (now Attock), Rawalpindi, and Jhelum dominated the recruitment flows that helped India send some 2.5 million soldiers to fight in World War II on behalf of the British Empire. The North West Frontier Province (NWFP) gradually began supplying troops and officers, as settled areas Pushtun tribesmen joined the military.
My research, based on official Pakistan Army data, indicates that by 1990 the percentage representation in the Pakistan Army as a whole (officers and Other Ranks or soldiers) was as follows: Punjabis 65 per cent; Pushtuns 14 per cent; Sindhis and Baluchis 15 per cent; Kashmiris 6 per cent; and Minorities 0.3 per cent.
Since then, with the provision of waivers for both physical and educational qualifications, recruitment has been increased from the formerly less well represented areas. Punjab shows an overall decline in recruitment of soldiers from 63.86 per cent in 1991 to 43.33 in 2005, with Central Punjab outpacing Northern Punjab, the traditional recruitment ground, by 7,500 to 5,000 recruits in 2005. Southern Punjab had 1,800 recruits. The NWFP and FATA increased from 20.91 per cent to 22.43 per cent, Sindh rose from 8.85 per cent to 23.02 per cent, with rural Sindh accounting for the majority of the recruits (5,095 to 2,500 in 2005), Baluchistan rose from 0.49 per cent to 1.52 per cent in 2005 with 200 urban to 300 rural recruits in 2005, and Azad Kashmir and the Northern Areas rising from 5.86 per cent to 9.70 per cent.
