Stats

In-game description

A 5.45x39mm BT gs (GRAU Index - 7BT4) cartridge with a 3.1 gram armor-piercing tracer bullet with a heat-strengthened steel core with a bimetallic jacket, in a steel case; intended for target designation and fire adjustment in battle (Trace color: Red). This BT bullet (Bronebóynaya Trassíruyushchaya - "Armor-piercing Tracer") it's an improved version of the used in the 5.45x39 mm T gs cartridge (GRAU Index - 7T3), since the lead core was replaced by one of heat-strengthened steel, providing automatic firearms with penetration capabilities against basic ballistic body protections as well as excellent results against intermediate models, however, due to its design, it has a significant bounce probability off various surfaces.

Against which armor

Penetration 37 is above the resistance of class 3 armor (30) — while such armor is intact, the round penetrates it more often than not. Against class 4, penetrations are rare until the armor is worn down.

For example, the vests it can defeat: BNTI Kirasa-N body armor, 6B23-1 body armor (EMR), BNTI Zhuk body armor (Press). The full table is in the armor classes guide.
