The sculpture, cast in reinforced concrete, has the shape of a gun and the physical reality of a building. The tank is both the SUBJECT and the OBJECT.

It is the kind of roughly assembled but authoritative platonic portrait seen in the models of ships and guns made by ex-servicemen.

It is a thing in itself but also a maquette for a sculpture as big as a building to be constructed and then bombarded by demolition equipment or a big gun to produce something which is both a tank (the subject) and a battered building (the object).
