Republican presidential candidate Rep. Ron Paul is out with a new ad that portrays him as a veteran who will secure America’s borders and rebuild its defenses.

The 30-second spot titled “Secure” includes flashing images of military helicopters and aircraft carriers.   The ad  states that America will not be the world’s policeman and spend trillions overseas.

Paul has said that he would end all military engagements around the world and bring every troop home.

Unlike most of his GOP rivals, Paul has advocated against building a large fence at the US-Mexico border.  Paul said in September at a GOP/ Politico debate that “fences may be used against us, keeping us in.”

More and more Paul has been highlighting his military experience. He mentioned it while campaigning recently in New Jersey and New Hampshire. He recently launched a 60-second TV ad touting his experience.

He served as a flight surgeon in the Air Force from 1963 to 1965 and in the Air National Guard from 1965 to 1968.

Paul’s campaign has done well fundraising among members of the military.  As of June 30, some of Paul’s largest campaign contributions were by those who identify their employer as being the U.S. military.

The campaign announced earlier this week that it had raised over $8 million in the last three months. Paul raised $4.5 million the previous quarter.

The campaign says that the “Secure” ad will begin airing today in the early primary states of Iowa, New Hampshire, South Carolina, and Nevada.
