Distinguish radar from direct vision

Radar reveals contacts but does not replace visual scouting for every detail. Keep scouts moving and investigate important contacts before choosing a costly response.

Information tools

Visual scoutIdentify units and structuresMust approach the target
RadarDetect contacts over an areaNot full visual identification
SonarObserve underwater threatsCoverage is local
Strategic zoomRead multiple frontsNeeds useful intelligence to display

Support shields with power

Shields consume energy and can fail when the grid is stressed. Add them to a sustainable economy, then avoid placing every valuable structure where one shield failure exposes the entire base.

Upgrade the ACU at a safe time

Commander upgrades occupy the ACU and consume resources. Begin them in a protected position with a viable economy rather than during a retreat or a large power deficit.

Check the victory condition

In assassination games, losing the commander loses the match even if factories and armies survive. Other settings change the objective, so read the lobby rules before treating the ACU as expendable.
