A theatre ballistic missile (TBM) is any ballistic missile with a range between 300 kilometres (190 mi) and 3,500 kilometres (2,200 mi) , used against targets "in-theatre". Its range is thus between that of tactical and intermediate-range ballistic missiles. The term is a relatively new one, encompassing the former categories of short-range ballistic missile and medium-range ballistic missile. Two examples of this type of in-theatre missile are the Soviet RT-15 and American PGM-17 Thor missile, both from the 1960s.
