By 1940–1942, soldiers generally used "jeep" for half-ton or three-quarter-ton Dodge Command Reconnaissance cars, with the three-quarter-ton Command Cars sometimes called "beeps" (for "big Jeeps"), while the quarter-ton cars were called "peeps", "son of jeep", "baby jeep", or "quads" or "bantams". A seven page article in "Popular Science" (Oct 1941) headlined introducing the quarter-ton as ""Leaping Lena"" – also one of the nicknames of the ubiquitous, same length Ford Model T – and further called it a buggy, or just a bug. Originally, "peep" seemed a fitting name, because the quarter-ton was considered primarily a reconnaissance (peeping) car.
