Scheme O is a tactical planning tool designed to help leaders rapidly build clear mission graphics and planning products. Instead of spending hours manually drawing terrain analysis and overlays, Scheme O allows users to construct tactical planning geometries in seconds. Built around real problems leaders encounter during mission planning, the platform focuses on speed, clarity, and predictable results. Key Features: Rapid Geometry Creation - Build planning geometries instantly using real weapon systems or custom parameters. Flexible Map Drawing - Create shapes, lines, and overlays that match the complexity of real terrain instead of forcing planning into rigid formats. Route Planning with Checkpoints - Plan routes with checkpoints, pace estimates, and time calculations to better understand movement across the battlefield. Integrated Planning Tools - Quickly place friendly and enemy positions, generate graphics reference grids (GRGs), and build planning overlays directly on the map. Close Air Support Planning -Integrate CAS considerations directly into the planning environment. Weather Integration - Pull weather data for specific days to support planning and analysis. Data Matrix Output - Automatically consolidate planning data into structured outputs that can be easily copied into orders, briefs, or planning documents. 3D Recon - Assess the terrain and see how your plan will actually look on the ground. Scheme O helps leaders spend less time drawing graphics and more time thinking about the fight.
