This is an editorial that represents one side of the argument.
Here is a better article in USNI that explains much better what the mission is becoming and the reform taking place.
““Where the commandant is going here is, if we’re going to be operating in a disaggregated environment, where you have 75 Marines operating throughout the first island chain, at times under duress, in competition and in crisis, and you need that really seasoned, mature decision-making capability, there is an age component to that,” Smith said.”
Quick shoot and scoot missions to hit Chinese ships or priority targets with the Naval Strike Missile...etc.
Also putting more organic firepower within 75-100 man units versus having firepower in a weapons company for the battalion.
Thank you.
