If you are in the market for any size of military surplus vehicle, keep an eye on GovPlanet. The online auction house is about to start selling US Navy and Marine Corps surplus M1161 ITV Growlers and seven-ton Medium Tactical Vehicle Replacement trucks.

Beginning in March, GovPlanet, which started selling military Humvees in 2014, will be the "exclusive source" for a fleet of retired ITVs and MTVRs, according to GovPlanet's website.

The M1161 ITV Growler is a 4x4 "jeep-style" vehicle with a Navistar 2.8-liter diesel, 132-horsepower engine. It is approximately 13.5 feet long, 5 feet wide, and 6 feet high. The ITV was developed by the American Growler company in 1999 and entered into service with the Marine Corps in 2009 as a utility, scout or fast-attack vehicle, according to a GovPlanet press release.

The MTVR is a 6x6, seven-ton cargo truck with a Cat C12 diesel, 410-horsepower engine. It is approximately 26 feet long, 8 feet wide, and 11.5 feet high. The MTVR entered into production in 2005 and is still in regular operation with the Navy and Marine Corps as a prime mover for the M777 howitzer, as well as troops, fuel, water and a wide variety of other equipment, the release states.

"This is obviously an extremely rare and unique opportunity to purchase highly [specialized] vehicles built for and used by the US military," said Doug Feick, senior vice president of new business and corporate development for Ritchie Bros., which owns GovPlanet.

"Following up on the success we achieved with the sales of the Humvee for the US Department of Defense, which garnered a ton of public interest and excitement, sales of the ITVs and MTVRs showcase our ability to provide innovative, best-in-class disposition solutions for the US government, as well as other federal, state, and local agencies," he said in the release.

Both the ITV and MTVR are currently on display at Ritchie Bros.' massive six-day onsite auction in Orlando, Florida. More than 13,500 equipment items, trucks and other industrial assets are set to sell in that auction.
