ミハイル・トゥハチェフスキー
In the early 1930s the RKKA command considered the idea of universal guns - i.e. guns which could be used both as field and anti-aircraft weapons. Mikhail Tukhachevsky, the head of the ordnance department between 1931 and 1934, ordered the development of universal (with 360° traverse) and semi-universal divisional pieces.
