这 军械 QF 4.5 英寸榴弹炮 was the standard British Empire field (or ‘light’) howitzer of the First World War era. It replaced the BL 5-inch howitzer and equipped some 25% of the field artillery. It entered service in 1910 and remained in service through the interwar period and was last used in the field by British forces in early 1942. It was generally horse drawn until mechanisation in the 1930s. The QF 4.5-inch howitzer was used by British and Commonwealth forces in most theatres, by Russia and by British troops in Russia in 1919. Its calibre (114 mm) and hence shell weight were greater than those of the equivalent German field howitzer (105 mm); France did not have an equivalent. In the Second World War it equipped some units of the BEF and British, Australian, New Zealand and South African batteries in East Africa and the Middle and Far East.

这 西科斯基 H-5, (initially designated R-5 and also known as S-48, S-51 and by company designation VS-327) was a helicopter built by Sikorsky Aircraft Corporation. It was used by the United States Air Force, and its predecessor, the United States Army Air Forces, as well as the United States Navy and United States Coast Guard (with the designations HO2S and HO3S). It was also used by the United States Post Office Department. In December 1946, an agreement was signed between the British company Westland Aircraft and Sikorsky to produce a British version of the H-5, to be manufactured under license in Britain as the Westland-Sikorsky WS-51 Dragonfly. By the time production ceased in 1951, more than 300 examples of all types of the H-5 had been built.
