What You Can Build
Ambush on a country road, urban combat in a village or crossing an open intersection – Phaseline turns any situation into a clean top-down overview.
Terrain & Infrastructure
Combine roads, dirt roads, trails, crossroads and driveways. Place houses, fences, courtyards and containers – from a single checkpoint to a complete village.
Units & Sectors
Markers for friendly forces, enemy forces and medics with custom abbreviations (PM, SAW, MED …), dockable labels and sector arrows for security sectors and fields of fire.
Maneuvers & Movement
Plot movement paths as solid, dashed or dotted lines with arrowheads – perfect for flanking maneuvers, bounding overwatch or crossing linear danger areas.
PNG Export for Briefings
One click, one high-resolution PNG. Share it directly on Discord, in your unit's forum or in the briefing slides for your next operation.
Who Is Phaseline For?
ARMA & Milsim Squads
Plan operations for ARMA 3, ARMA Reforger, Squad or Hell Let Loose: visualize formations, axes of attack and fallback routes before the first shot is fired. Perfect for units with a structured briefing routine.
Airsoft Teams & Game Masters
Create field overviews with respawns, mission objectives and restricted zones, or brief your team before the match with a clear tactical map – easy to understand even for rookies.
Instructors & Tactics Nerds
Illustrate battle drills, reactions to enemy contact or crossing linear danger areas – step by step, phase by phase, as an image series.
How It Works
Build the Terrain
Drag road segments, crossroads and buildings from the palette onto the canvas – grid snapping keeps every piece perfectly aligned.
Draw the Situation
Place unit markers, align sector arrows, plot movement paths and add labels.
Export & Brief
Export as PNG and share it with your squad. Scenes can be saved and edited later for the next phase.
