The BMP-23 (бойна машина на пехотата) is a Bulgarian infantry fighting vehicle which was first introduced in the early 1980s. However, it was based on a design from the Bulgarian design bureau from the 1970s, being presented in 1980s. The hull is based on that of the Soviet 2S1 self-propelled howitzer (also produced by Bulgaria) with thicker armour and a more powerful diesel engine, which is itself based on a stretched MT-LB chassis. Since the 2S1 is a larger vehicle, the troop transport compartment is not as cramped as that of the BMP-1. The armour is made of welded rolled steel, capable of withstanding heavy machine gun fire. {{Cite web |date=2013-01-02 |title=BMP-23 infantry fighting vehicle (Bulgaria) - Jane's Armour and Artillery |url=http://articles.janes.com/articles/Janes-Armour-and-Artillery/BMP-23-infantry-fighting-vehicle-Bulgaria.html |access-date=2023-01-14 |archive-url=https://web.archive.org/web/20130102175419/http://articles.janes.com/articles/Janes-Armour-and-Artillery/BMP-23-infantry-fighting-vehicle-Bulgaria.html |archive-date=2 January 2013 }}
