This reaction is expected from fresh non battle hardened troops , once they have some combat experience they will start pumping round instead of running .
But we can't always depend upon such engagements to give our men battle experience and exposure that's where large scale combined arms live fire drills come in .
One of the main reason why USMC is such lethal is coz they do it extensively and thus are very squared away when it comes to SOPs , leadership and reacting to various scenarios , But i am still waiting to see our men try out something even remotely similar .
