1.1.0
September 17, 2026
v1.1.0 — BinoView. Put the binos up on every fire mission. Tap OBSERVE on the mission map and you are behind 7x binoculars from your OP, looking at real terrain. M22-style mil reticle. Pan the sector, tilt, cycle 7x / 12x, lase the target for range. The optics are honest. The reticle ticks are true mils, the terrain is rendered at the same scale, and targets are sized by mil relation. A tank at 700 m is ten mils long, not a cartoon. Read the width off the reticle, apply W x 1000 / mils, then lase to check yourself. That is the drill. Targets sit on the ground where they belong. From an elevated OP the road, treeline, or hill at the target's range is below the skyline, and that is where the binos open. Short rounds land short. Overs land over. You will see it. Effects on target. When rounds score, vehicles and bunkers flash, then burn with a smoke column. Personnel go down. Dust hangs at the impact. Misses splash where they land, so a correction reads the way it does through real glass. Eleven scenarios each have their own photoreal panorama composed for the mission: the MSR for the convoy, the wood line for the treeline fights, the crossroads for the light armor, the river for the crossing, moonlight for the night patrol. Also in this release: dependency updates for the current SDK. Built by a 13F with 20 years AD. Standards-only. Doctrine governs.
