Private Park Hyun Jun Operator Guide

Primary Deployment: Korean Peninsula Frontline

Combat Role: Assault

Signature Weapon: Kastov 762

Operator Background & ROK Service

Private Park Hyun Jun is a frontline combat infantryman in the Republic of Korea (ROK) Army, attached to the Sierra-1 joint liaison squad alongside US Marine Corps operatives Reggie West and Joseph Dunn. Mobilized during the initial hours of the northern peninsula breach, Park represents the grounded grit of frontline soldiers defending urban civilians across trench perimeters.

Combat Role & Signature Weapon Handling

Operating as a dedicated frontline Assault specialist, Park specializes in sustained automatic fire with the Kastov 762. In the new Ballistic Authority framework, Park benefits from minimized initial barrel rise during tactical slide-to-crouch transitions and reduced aim flinch when mounted against fortified barricades.

When mounting cover in trench warfare, activate tactical stance to tighten close-range bullet spreads without sacrificing peripheral radar vision.

Tactical Loadout Synergy

Park pairs naturally with the Smoke Wall and SAM Airburst Turret field upgrades. Deploying smoke allows safe movement across exposed open mudflats while mounting heavy assault rifles ensures high-velocity armor penetration against incoming motorized squads.

Campaign Progression Role

Park serves as the primary perspective for Act I missions including Operation Entrenched. His progression unlocks Tier-2 perks such as Fast Hands and Birdseye, accelerating weapon swap speeds during intense close-quarter bunker sieges.
