Navy SEAL, Green Beret killed in Afghanistan, leaving Marine brother 'Sole Survivor'

As the sole survivor, Beau Wise was told he would not be put in harms way -- the only service member to be kept from combat in the Afghanistan war for such a reason.

Five-year-old Beau Wise's big brothers were more than big. Looking at Jeremy and Ben, 10 and eight years older, he saw grand, invincible figures -- figures who led Beau into no small measure of brotherly mischief. "I was kind of constantly getting pulled into various different shenanigans ... mostly instigated by Jeremy. He was definitely the biggest troublemaker of the four of us," Beau told ABC "This Week" Co-Anchor Martha Raddatz. Beau recalls the time eldest brother Jeremy threw him down the laundry chute as part of a daring Halloween candy caper perpetrated on their only sister, Heather. Thankfully, the more pensive Ben, the middle brother, had covered the hard basement floor with laundry before young Beau came tumbling down the chute. When the plot inevitably was foiled by parents, Jeremy and Ben absorbed the brunt of the punishment.
