Over the past years, APS has made rapid strides in technological advancements, thereby leading to a much more efficient system of communication. Army post offices in the Western Command have been provided with multi-purpose counter machines and most of the operations and telegrams transmission have been computerised.

Further, nearly 20 post offices are in the process for activation as e-Post Centers for transmission of e-post articles in the command. Also on the anvil is the establishment of a data centre, enlarging e-Post and banking facilities to the field areas as well. Automation of Field Post Offices (FPOs) and 1 CBPO and various APS units in Western Command is also being undertaken on priority.

Although the APS came into existence as a separate Corps on March 1, 1972, the FPO is more than 150 years old. The first FPO was raised in 1856 initially as a war-time organisation accompanying the Indian Expeditionary Force abroad. Thereafter in J& K operation of 1947-48, the organisation of FPOs was initially affiliated to Army Service Corps and the APS personnel were finally declared combatants in 1950. Further, on 1st July 1969, the collection, transport and delivery of official mail (SDS) was taken away from Signals and entrusted to APS.

APS is an integral part of the Indian Army and functions as an extension of the Department of Posts (Ministry of Communication & IT) to meet specific needs of the Armed Forces (Army, Indian Air Force, Indian Navy), Border Road Organisation and para-military forces.
