That is probably what he is after. He is the new kid on the block and can get away with asking for an increase in force.
No, Conway is not the new "kid on the block." He's been around for a long time and is well respected both inside and outside the Corps. He commanded I MEF during the drive to Baghdad in 2003, and worked very closely with his 1st MarDiv commander General Mattis to completely steamroll Saddam's Republican Guard and Fedayeen up Routes 1 and 7. Like all of our other top military commanders who are on the spear tip of GWOT, the public at large has almost never heard of men like Conway or Mattis, who in my opinion are equivalent to Bradley and Patton during World War II.
CNN video butchering aside, Conway knows exactly what he is talking about, and if he says that there is a big problem brewing with the Corps right now, then we can only disregard his warnings at our own peril.
