Hailing from Haryana, Mr Singh served in the Army for 14 years.
He decided to join politics after retiring from active service following the loss of hearing ability during the 26/11 rescue operation.
The AAP candidate is quite confident about his prospects in the December 4 polls.
"For the 2008 elections, there were around 75,000 voters in Delhi Cantt, out of which 10,000 were armymen. This time, out of around 1.25 lakh voters, almost 45,000 are army personnel," he said.
"The whole army votebank and the public which has full faith in it (the Army), will vote for me," he said.
Mr Singh said his priority, if he were to win, would be to work for the education and health sectors.
