Though not a combat arm, the Pioneer Corps provide disciplined and well trained manpower where civilian labour is either not available or its employment is not desirable for reasons of security.
The twelve Indian Pioneer regiments in existence in 1914 were trained and equipped for road, rail and engineering work, as well as for conventional infantry service.
While this dual function did not qualify them to be regarded as elite units, the frequency with which they saw active service made postings to pioneer regiments popular with British officers.
It was concluded that the Pioneer battalions had become less technically effective than the Sappers and Miners, but too well trained in specialist functions to warrant being used as ordinary infantry.
[11][12] In 1999 during Operation Vijay, two Pioneer Companies worked non-stop along with Border Roads Organisation to ensure that the lines of communication on the Srinagar-Leh, the Jammu-Poonch-Rajouri and Jammu-Srinagar areas remained open at all times.
