I enjoy finding tanks and other armored fighting vehicles on display - usually at various veterans' organizations. This one is at Maryland Army National Guard Armory in Frederick, MD. I stopped at this one on the home from the 2011 Maryland Geocaching Society Summer Picnic.
LOGGING REQUIREMENTS: Visit the site in person. On the front of the tank, you will find a pair of two hooks. There is a 3 digit number "etched" into the rear of the vehicle (right side). That will serve as your Log Password. In addition to this, you will need to post a photo of you and / or your GPS with the tank. Be sure not to include the info needed for the Log Password in your photo.
ABOUT THE M114: The M114 was designed to be fast and stealthy. Like the larger M113, it was swim capable and deployable by parachute. But unlike the M113 which became one of the most successful armoured vehicles, it quickly proved unsuited to use in the Vietnam war, and was replaced in the reconnaissance role by the M551 Sheridan light tank.
The M114 is a lightweight, low-silhouette vehicle, designed to complement the M113 in command and reconnaissance roles. It looks like a sleeker, lower M113. It can swim, propelled by its tracks, and is light enough to be transported by cargo aircraft and dropped by parachute. The M114 commander's cupola required that the hatch be opened to fire the .50 cal machine gun. The commander's hatch rotates 360 degrees with its .50 caliber machine gun and mount. The M114A1 allowed the firing of a .50 cal machine from the inside utilizing manual traverse and elevating mechanisms. The M114A2 (aka M114A1E1) had a hydraulically powered cupola and mounted the 20mm cannon M139. The observer in the rear had an M60 7.62mm machine gun mounted on a pedestal. There was stowage on the rear door for three M72A1 "LAW" anti-tank rockets.
The M114 is constructed of aluminum and weighs 13,100 lb (5.94 metric tons) empty, with a combat weight of 15,093 lb (6.846 metric tons). It is powered by a Chevrolet V-8 motor with a 283 cubic inch displacement. Engine was rated at 160 horsepower. It had a three-man crew, and a top speed of 36 mph (58 km/h).
