Since the early 21st century, most NATO armies have settled on
155 mm (6.1 in) weapons as having a good compromise between range and destructive power whilst having a single calibre, which simplifies logistics; however some military forces have retained 105 mm (4.1 in) towed howitzers for their lighter weight and greater portability, including their rapid
airlift and
airdrop capabilities. The lower power and shorter range of 105 mm (4.1 in) ammunition has led to its obsolescence in full-sized
self-propelled guns, such as the American
M108 howitzer and British
FV433 Abbot SPG. China, North Korea, Russia, and other former
Soviet bloc countries use 122 mm (4.8 in) and 130 mm (5.1 in) calibre weapons in similar roles.
