@ Mark · HUD demo

How it works

• Click the scene, the minimap or the satellite view. All displays update together.
• Say Mark @ 8828 (push-to-talk: hold Space). The agent replies Copy, Mark @ 8828.
• A mark is a short reference for a 10 m cell, made for close-in use. Say it or type it with or without the word “mark”.
• Key shifts the digits so the same place reads differently to anyone without the key. It is tokenization, not encryption.
• Format: @xxyy. The first two digits are the Easting, the last two the Northing. So @1828 is E 18 and N 28, and @0000 and @9999 are always SW of @1111.
• Rotate: drag the view left or right, twist the minimap, spin the dial, use the slider or the ← → keys (Shift = bigger steps). Or say turn left 45, face south, heading two seven zero, turn around. It loops a full 360° back to the original view.
• Zones: the amber lines are the real MGRS 1 km grid lines. They fall wherever they fall, so close-in points cross them constantly. The cyan square is your anchor zone, 1 km centered on you, and the circle is the 500 m range where a bare four-digit mark is safe. A mark never cares where the amber lines are. Directions use grid north.
• Logic: the viewer's own mark (YOU) anchors everything. Each code resolves through a 100×100 lookup table to the nearest place with those digits, within 500 m. Amber dashes are 1 km zone edges, so a mark can sit in the neighboring zone.
• Other phrases: Show marks, Remove marks, Mark hazard @ 4410, Set key Falcon.
• Drone view: an overhead feed of the same ground. Click it to drop a mark, and the same @ code appears in the HUD, minimap and satellite views. Drag to pan, use + and − to zoom, and switch the feed between EO and IR.
• Blocked view: choose Hill or Building under Soldier’s view. The scene is blocked, but each mark still shows its direction and distance, and the card reads Blocked.
• Voice and radio: Where am I, Where is @9116, How far to @9116, Point me to @9116, Is @9116 north or south of me, What is the LZ, LZ is @3812, Two bogies @3123, 3421. Press Play call-out for a sample exchange.
