The Zak ady Mechaniczne "Tarnów" UKM-2000 is a 7.62x51 mm NATO general purpose machine gun with STANAG 2324 designed in Tarnów, Poland. The name stands for Uniwersalny Karabin Maszynowy 2000 ("Universal Machine Gun model 2000"). When on March 12, 1999 Poland joined North Atlantic Treaty Organisation a problem arose with modifying the weapons of the Polish Army to use standard NATO ammunition. A decision was made to develop a new general purpose machine gun. The construction was based on the design of the successful and battle tested PK/PKS machine gun. The UKM-2000C is a secondary arment of KTO Rosomak IFV.
