They’re using 5.56 NATO rifles and ammo , and in Ukraine that mostly means standard infantry rifles plus some imported models like M4-pattern rifles, CZ Bren rifles, and German Haenel MK 556s used by some units. There’s also a newer Ukrainian 5.56 anti-drone round, nicknamed Horoshok , designed to fragment in the air and help against FPV drones.
What that means
- 5.56 NATO is the common Western rifle caliber Ukraine uses for a lot of its infantry weapons.
- Some Ukrainian troops, especially SOF and air assault units, have been seen with AR-style rifles and MK 556 rifles from Germany.
- The newer Horoshok round is made for drone defense, not for replacing regular ammo across the board.
In plain terms
If you meant “what exact 5.56 setup,” the answer is: a mix of NATO-standard 5.56 rifles and ammunition, plus new anti-drone 5.56 rounds being introduced.
TL;DR: Ukraine is mainly using standard NATO 5.56 rifles/ammo , with some M4/Bren/MK 556-type rifles , and they’ve also started using a special 5.56 anti-drone round called Horoshok.
