Just click video response and upload your question," asks the page.

At the urging of Defense Secretary Robert Gates, the Pentagon this year has expanded its presence in online social networks like Twitter and Facebook. Mullen and Price Floyd, a top Pentagon public relations official, are both on Twitter. The Defense Department also launched its redesigned website on Monday.
While the Pentagon is using the web to engage with more Americans and reach a younger audience, some concerns have arisen that the efforts could pose security issues.
The U.S. Strategic Command issued a "warning order" in July that suggested the military should ban social networking sites due to security concerns. A day later, the Marine Corps enacted a unilateral social media ban in response to the report.
In the wake of these actions, Mullen reassured his Twitter followers that he would continue to use the service.
