Use vision before movement

Fog hides units outside vision. A movement path can run into an unseen enemy and stop unexpectedly, so reveal the route with scouts before committing a tank or transport that must reach an exact tile.
| Tool | Benefit | Best use |
|---|---|---|
| Recon | High movement and vision | Probe open routes carefully |
| Infantry on mountains | Expanded vision | Observe nearby ground approaches |
| Flare | Reveals an area around its shot | Check concealed choke points |
| Captured radar | Improves visibility | Support the wider army's information |
| Adjacent unit | Reveals concealed nearby enemies | Inspect woods, ruins and reefs |
Check concealment terrain separately
Woods, ruins and reefs can hide units even when the tile falls within ordinary sight. Adjacent scouting or an appropriate reveal effect is needed; visible terrain does not guarantee visible occupants.
Use flares to reveal a useful area
A flare shot reveals a small area around its landing point. Aim at the choke point, property cluster or hidden artillery position that changes your plan, rather than lighting empty ground far from the current front.
Combine terrain defense with range checks
A defensive tile helps ground units survive but cannot make a bad matchup safe by itself. Count indirect-fire range and escape routes before parking an expensive unit on a city or in a forest.
| Terrain or feature | Effect to consider | Response |
|---|---|---|
| Woods | Concealment in fog | Scout before entering |
| Ruins | Concealment in fog | Check for hidden defenders |
| Reefs | Naval concealment | Approach with appropriate scouting |
| Meteor shard and plasma | Blocks routes | Destroy the shard to remove linked plasma |
| City | Ground repair and defense | Hold it without ignoring enemy artillery |
