Following World War II, plastic manufacturing was seen as an industry with growth potential with many old and new companies making plastic figures that were widely available in the United States. Army men following the war were sold unpainted, usually in a green color corresponding to United States Army uniforms in World War II. Plastic figures were sold en masse in clear plastic bags with an illustrated header card in different sizes and prices.
Beginning in the early 1950s, Louis Marx and Company sold boxed sets of figures and accessories called playsets, such as "US Army Training Center" and the later the "Battleground" sets.
The economy of plastic sold in bulk, popularity of army men, and competition with manufacturers led to army men being sold in large bags by Marx, Tim Mee, Ideal, Lido and MPC for as little as a penny a piece in the mid-1960s. During this time, Marx gave the American army men actual enemy soldiers to fight such as German soldiers (molded in grey) in their 1962 "Army Combat" set and Japanese enemies (molded in yellow) in their "Iwo Jima" set that was released in 1963. In 1965, a "D-Day" Marx set featured Allies such as French (horizon blue), British (khaki), and Russians. One of their last and largest playsets was the multi-level "Fortress Navarone" mountain set based on The Guns of Navarone, which was available in the 1970s and pitted World War II Americans against Germans.
