All infantry battalions have an ATGM platoon of eight launchers presently equipped with Konkurs. The same eight launcher in Mechanised infantry becomes a company. Many officers and NCO/JCOs attend ATGM courses. Missile badges are authorized after one fires a missile. The problem is that one does not get a training missile to fire in normal course because of non availability. They can put on the badges after firing a missile . But Infantry is one organisation which does not live in false sense of laurels such as missile badges. Their lives and careers are full of so many vagaries to care for a piece of ribbon as life time achievement.
All hollow charge warhead such as 84mm RL, 106mm RCL and single warhead missiles are ineffective against RCC bunkers. Tandem warhead missiles can bring down a Sangarh but not a good RCC bunker. A kinetic shot from tank is much effective. Even fire from canons like 30mm or 40mm canon is more effective.
