Well if we get Field Artillery i want this:
German K5(E) 280-mmCountry of Origin: Germany
Caliber: 11.02 inches (280 mm)
Barrel Length: 70.08 feet
Overall Length: 135.28 feet

Shell and Weight: HE; 563.38 lbs

Notes: This was one of the best workaday railway guns ever built. The K5(E) formed the background of the German railway artillery force during World War II and saw wide use. Two examples of the K5(E) survived World War II. One K5(E) is on display at Cap Griz Nez in France, the other "Anzio Annie" (above) is on display at the Aberdeen Proving Grounds Museum, Aberdeen Maryland. This particular gun is the one that was used in the shelling of the US troops during their landing at Anzio, Italy.
