You said it. Waiting at the LZ as an eagle flight lands as a group. The Hueys all flaring for a landing and the music of the blades is deafening, you feel the ground shake and your insides quivering to the beat of the rotors. Yep, those were the days that being an Air Mobile Infantryman existed. Is it weird to sometimes miss them ?.
I admired you infantrymen, I know when you heard that distant helicopter coming in to take you back to base was the best sound ever!
Vietnam and it's sounds will live with us forever.
