Chairman of the Joint Chiefs of Staff Adm. Mike Mullen released video of his virtual town hall in which he collected questions about the U.S. military submitted via YouTube, Twitter, and Facebook.

Mullen, who is a proponent of new media outreach on behalf of the Pentagon, announced the town hall in August.

The top military official tweeted Monday:

You asked, I answered. Ask the Chairman: A Virtual Townhall aired today on the Pentagon Channel.

Mullen took several questions from active military members and inquires about the wars in Iraq and Afghanistan.

At the behest of Secretary of Defense Robert Gates, the Pentagon has expanded their outreach to younger Americans using social media in a number of ways, including a launching a new website integrated with the new media sites.

Though top Defense Department officials have pushed the use of social media tools, the U.S. Strategic Command issued a "warning order" in July that suggested that the military ban the use of such sites due to security concerns. The Marines enacted a unilateral blackout of the sites in response to the report.
