Respected Sir, there is no such thing as professional soldiers only fire with aim. There are tactics which involve blind firing or least the aim less firing at the target area so that the enemy is CONFUSED OR PINNED DOWN so that other friendly soldiers from that team (platoon or section) flank them out since enemy is confused shooting at the soldier that is firing aimlessly.
Anyway this isn't video game where one soldier just moves on firing and aiming since they have fuel meter but in real life its HARDCORE Team death match one shot is enough to kill or cripple one soldier.
Now whether you agree with my saying or not it doesn't matter Pakistan army is one of the most professional forces in the whole world and it has been more successful in suppressing terrorism in Pakistan that whole NATO in Iraq or Afghanistan.
