Defence Minister A K Antony has also sent two letters to the MP who has been demanding denotification of the firing range which is available with the army till 2020, they said.

About 10 years back, the Army had 104 ranges but the numbers have come down to 66 including 12 acquired and 54 notified ranges.
Thirty-eight field firing ranges have been taken away from the army and re-notified in this period, they said.
The issue of shortage of these ranges also came up for discussion during the ongoing Army Commanders' Conference.
