Indian Army fired Excalibur precision guided ammunition from M-777 artillery howitzers in Pokhran firing ranges in Rajasthan on December 09.  Excalibur penetrates 8-10 inches thick concrete walls and reduces chances of collateral damage when used against the enemy. The holes on the rooftop showed concrete penetration capability of the ammunition, which can be fired only from M-777 howitzers. The ammunition was fired at both concrete and sand bunkers.
