They ARE all amongst the best and the bravest helicopter pilots and crewmen in the US Army,but they are far from being the only ones. There are many,MANY pilots and crewmen serving in other units who are just as good and just as courageous,but there are only so many slots available in the 160th,and people who may own homes and have an established life with a wife and children at other bases may not want to disrupt the lives of their families with a move.
It's not taking anything away from the men of the 160th to say this.
