Official Workshop description
Three configurations are available for both the USSR and US factions:
- Manual optical fire control, without a protective cage.
- Manual optical fire control with protective cages.
- Modernized fire control computer, revised cages and camouflage netting.
The US faction versions use Ukrainian markings. They retain the base game's US faction key so server configurations can provide their preferred faction replacement.
Features
- Forty launch tubes, single fire and selectable ripple quantities.
- Optical targeting and ballistic information.
- Modernized variants add a physical fire control display with ballistics, tactical map, optic, status and rear camera pages.
- English, Russian and Ukrainian interface text.
- Game Master rocket loading, unloading and rearming actions.
- Both faction vehicle catalogs and the Game Master browser include all three variants.
