This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces.

The Army's Anti-aircraft command, which was under command of the Air Defence UK organisation, grew to 12 AA divisions in 3 AA corps. 40-mm Bofors entered service in increasing numbers. In addition the RAF regiment was formed in 1941 with responsibility for airfield air defence, eventually with Bofors 40mm as their main armament. Fixed AA defences, using HAA and LAA, were established by the Army in key overseas places, notably Malta, Suez Canal and Singapore.

paragraph_text: Neoclassicism also influenced city planning; the ancient Romans had used a consolidated scheme for city planning for both defence and civil convenience, however, the roots of this scheme go back to even older civilizations. At its most basic, the grid system of streets, a central forum with city services, two main slightly wider boulevards, and the occasional diagonal street were characteristic of the very logical and orderly Roman design. Ancient façades and building layouts were oriented to these city design patterns and they tended to work in proportion with the importance of public buildings.

paragraph_text: Casagrande claimed that he volunteered for the Bosnian Croat Defence Forces HVO in 1993 after his service in the Finnish Army.

After becoming under suspicion he claimed that the book was in fact a work of fiction. The truth about Casagrande's involvement in the war remains uncertain.Later Casagrande has expressed views condemning war crimes: "Those troops know that they are doing wrong. This is the very opposite of constructive collectivity and group spirit. Anybody can understand that it is by no measures militarily efficient to go kicking the doors of old people's home." Casagrande has been lecturing in the National Defence University of Finland since 2006 on courses of strategy and leadership.

paragraph_text: Most Western and Commonwealth militaries integrate air defence purely with the traditional services, of the military (i.e. army, navy and air force), as a separate arm or as part of artillery. In the United States Army for instance, air defence is part of the artillery arm, while in the Pakistan Army, it was split off from Artillery to form a separate arm of its own in 1990. This is in contrast to some (largely communist or ex-communist) countries where not only are there provisions for air defence in the army, navy and air force but there are specific branches that deal only with the air defence of territory, for example, the Soviet PVO Strany. The USSR also had a separate strategic rocket force in charge of nuclear intercontinental ballistic missiles.

Area defence systems have medium to long range and can be made up of various other systems and networked into an area defence system (in which case it may be made up of several short range systems combined to effectively cover an area).
