Wg Cdr Pushpendra Singh Diwaniyan has been commanding one of the first OSA-AK-M air defence squadrons of the IAF with effect from 14 May 90. He has flown 6600 hrs on various aircraft, all accident/incident free.

While posted as Flight Commander in a Helicopter unit during Nov-Dec 85 in 'OP MEGHDOOT', Wg Cdr PS Diwaniyan carried out 1000 hazardous missions to deliver over 1500 tons of vital supplies like guns, ammunition, rations and medicines to various helipads in Siachen Glacier considered one of the highest DZs/helipads in the world. During Nov 85, he carried out the first ever successful paradrop of eight snow-mobikes to high helipads like Chandan, Jawala, G-3, Kumar, Sai-la etc. in a very close proximity to enemy locations in situations invariably similar to warlike conditions due to frequent enemy shelling/fire, from altitudes ranging from 18000 to 21000 ft. well above the ceiling of Mi-17 helicopters. This resulted in enhanced operational mobility of the Army patrols between posts, near the actual line of control, on the Siachen Glacier.

Ever since taking up the assignment as OC of OSA-AK-M squadron, the officer has gone methodically and with a great zeal in moulding his unit into a viable operational squadron capable of meeting its assigned air defence task.

Wg Cdr Diwaniyan has had the unique distinction of being parade commander of the Air Force Day investiture parades, the President's Colour presentation parade and a number of Guard of Honours presented to foreign Heads of States.

For his courage and exceptional devotion to duty, the President is pleased to award Vayu Seva Medal to Wg Cdr Pushpendra Singh Diwaniyan.
