The KPM-12 Steadfast is a battle-DMR hybrid that sacrifices extreme accuracy for sustained-fire capability. Where conventional DMRs are precision instruments that demand careful shooting, the Steadfast is designed for designated marksmen who operate as part of assault elements and need to maintain precision fire while moving and shooting rapidly. The weapon chambers 7.62mm caseless with a heavy barrel that resists thermal shift during sustained engagement.

The Steadfast's BCI integration focuses on moving-target engagement rather than static precision. The AI tracks target movement vectors and provides a continuously updated lead indicator in the neural overlay, allowing the marksman to maintain effective fire on moving targets at ranges up to 500 meters. The weapon's 1.5-MOA accuracy is modest by DMR standards but maintained consistently through high round counts and rapid-fire sequences.

Kang-Petrov prices the Steadfast at Φ3,500, positioning it between their Equalizer and premium competitors. Its customers are operators who need a marksman's reach with a rifleman's tempo — squad-level marksmen who engage targets of opportunity while keeping pace with their assault element rather than providing static overwatch. The weapon fills a role that traditional DMR doctrine doesn't acknowledge: the moving marksman.
