The first thing you need to know about Navy Lt. Brad Snyder is that he's a bit intense.

If you go to the U.S. Naval Academy, swim competitively, and make the cut for the Navy's elite bomb-disposal squad, you're probably going to be the competitive type.

"Crossfit, surfing, biking, running, swimming, you name it I'm into it. Rock climbing," says Snyder.

The second thing you should know is that Snyder plans to continue doing all these things — even though he's now blind.

On a placid summer morning last month, before the Virginia heat could hit them, a former U.S. Marine and his partner lifted their rowing scull into the glassy water of the Rivanna River, near Charlottesville.

"First thing I do is take these legs off," said Rob Jones, who like his rowing partner, Oksana Masters, is a double, above-the-knee amputee. They're the U.S. team for mixed-doubles rowing at the 2012 London Paralympics, which started Wednesday.

Homeless veterans of the Vietnam War have been a face of American poverty for decades, and now some veterans of a younger generation are dealing with the same difficult issues.

"I had my apartment up until 2011," says Joshua, a 28-year-old Navy vet, who asked not to give his last name because of the stigma of being homeless. "[I] couldn't keep up with the rent; I did a little couch surfing and then ended up on the street for a while."

Nearly two years ago, Afghan President Hamid Karzai ordered that gun-toting private security companies in his country be brought under state control. But the Afghan force to replace the foreign-funded contractors is off to a rocky start.

According to the U.S. Special Inspector General for Afghan Reconstruction (SIGAR), the new force will increase security costs for USAID projects and could even shut some of them down, at a loss of about $899 million. USAID in Kabul disagrees, and the dispute has gone public.

The ministry that governs religious affairs in Afghanistan has announced what some are calling a "three strikes" policy.

It's a warning directed at Muslim clerics, or imams, accused of inciting violence in their Friday sermons. Imams across the country routinely condemn the U.S. presence in Afghanistan and speak in favor of the Taliban.
