Russia used a North Korean KN-23 ballistic missile during an attack on Ukraine on July 31. The rocket did not reach its target. This information was conveyed by "Defense Express," which emphasizes that Russia rarely uses this missile.

The Bulsae-4 is uniquely North Korean. It borrows the chassis of a North Korean version of the Russian BTR-80 armored personnel carrier—and adds a bulky top turret with eight anti-tank guided missiles, each likely weighing tens of pounds and ranging several miles.

The Bulsae-4 is a Non Line of Sight (NLOS) anti-tank guided missile (ATGM) with an estimated range of over 10 kilometers. It appears broadly equivalent to the U.S. FGM-148 Javelin and Chinese HJ-12.
