Indian army in 1962 War, why didn't Indian army increase number of Sten guns, Bren LMGs issued to infantry sections and use Cup grenade dischargers?
Talks on 1962 war generally revolve around how underprepared Army was or airforce was not used.
But there was one quick fix that could have been easily done to mitigate lack of self-loading rifle and other short comings to a great extent, increase number of Sten guns and Bren LMGs per infantry section.
Instead of conventional 1 Bren LMG, issue 2 Bren LMGs and instead 2 Sten guns per section, issue 4 Sten guns. Since every Indian soldier was trained to use Bren Gun and Sten gun and India was also producing Bren gun and Sten guns plus thousands already in reserve, it wouldn't have been a major challenge, equal to arming every soldier with SLR.
Also one Lee Enfield cup grenade discharger could have been issued per section with blank rounds to fire standard infantry 36M hand grenades up to 90-100 meters away. In both world wars, all countries used rifle grenades including Britain. Japanese in WW2 used Type 89 grenade dischargers per squad. It was probably the most effective weapon Japanese infantry had.
A conventional Indian infantry section has 7 to 8 Lee Enfield rifles, 1 Bren LMG and 2 Sten guns, 1 or 2 pistols, plus couple of hand grenades per soldier. Make it 2 bren LMGs, 4 Sten guns, 4 Lee Enfield rifles with 1 cup grenade discharger with blank rounds plus grenades. This is to compensate lack of a standard issue self-loading rifle and often inadeqaute artillery support.
If this was done, 1962 war could have been a partially successful defensive war instead of the collaspe that it was.
