The best artillery gun system in the world!

Background:     

Development: 

After World War II the South African Army used the British 140-mm (5.5-in) medium gun with a maximum range of 16460 m (18,000 yards) and the 25-pdr (88-mm) field gun with a maximum range of 1225Cm (13,395 yards). As South Africa become more involved in what became known as the Border war, the South Africans, found themselves outranged by enemy artillery and rocket fire of the most modern Soviet design. As no Western power would supply S.A. with modern equipment, the local industry developed indigenous systems to counter the Soviet threat. First of these systems, the G5 155-mm (6.1-in) gun/howitzer and the 127-mm (5-in) 24-round multiple rocket system, developed into world class products and saw extensive combat during the Border war.
 
Initially the G5 owed much to the Canadian Space Research Corporation GC 45 155-mm (6.1-in) weapon, which are in service with the Thai Marines. However, South Africa added so many additional features and constantly refined the gun over many years of battle experience that the G5 bears very little resemblance to the original Canadian weapon. The gun has a 45-calibre barrel fitted with a single-baffle muzzle brake and an interrupted-thread breech mechanism. To the rear of the breech is a pneumatically-operated rammer to ram projectiles into the chamber at all angles of elevation; this is powered by an air bottle mounted on the right trail. The bagged charges are loaded by hand.
