"In early March, photos circulated online depicting MT-LBs with 2M-3 naval turrets welded to their roofs. The 2M-3 is two 25-millimeter auto-cannons, one atop the other in an enclosed casing. The 2M-3 made its debut in 1953."
This is an upgrade (?) on the modified MT-LB mentioned upthread. From the piece:
"The first of these weirdo MT-LBs started showing up in Ukraine last month. On or before Feb. 3, Ukrainian forces in Vuhledar captured from hapless Russian brigades a 13-ton, two-crew MT-LB sporting a 2M-7 gunboat turret.
The 2M-7 is an over-under pair of 14.5-millimeter machine guns behind a steel shield. It entered service with Soviet forces in 1945."
