The TACAM R-1 (Tun Anticar pe Afet Mobil R-1 – "Anti-tank gun on R-1 mobile gun carriage") was a small tank destroyer for use by Romania during World War II. It was designed on 22 November 1943 at the request of the Romanian General Staff. Fourteen R-1 vehicles were to be rearmed with 45 mm 20-K guns. Although this vehicle was designed to be used only for security duties, the project was cancelled because it was eventually regarded as a waste of badly needed industrial capacity, the 45 mm gun having been obsolete against most Soviet tanks by then.^[1]
