Strengthening

Strengthening is a local trench upgrade rather than a global building unlock. Its description states: “The trench is reinforced with supports and a roof, turning it into a small bunker.” The source is build 23882143. The linked component adds two garrison seats, taking a trench from one to three. Research costs 120 minerals and six seconds. Its configuration includes a required configuration and applies to the local object. It therefore does not establish that one purchase upgrades every trench. The description’s bunker wording characterises the reinforced trench without turning its identity into the separate Bunker building.

A standard trench houses one squad, a Bunker five, and local Strengthening raises the trench to three, from build 23882143. The English phrase “a small bunker” describes that result without equating every attribute with the Bunker. Capacity is a verified linked-component effect, not evidence of identical armour, repair or electricity requirements. This section records a clarification of the upgrade mechanism from extracted data rather than a measured balance change between game versions. A local upgrade should be assessed on the particular trench receiving it.

A trench costs ten minerals and six seconds, and Strengthening acts locally rather than automatically across an entire line. The upgrade at 120 adds two seats, while a separate Bunker at 120 houses five squads. Our advice is to reinforce an already useful position and compare capacity purchases separately. The original trench’s area-resistance coefficient of 0.6 remains a source parameter. The addition of a roof does not by itself prove an undocumented defensive bonus or a new damage formula.

A strengthened trench can hold three squads instead of one, but its actual garrison still needs scouting. The patch note of 22 June 2026 says covered units no longer die from environmental flame and gas. That limitation concerns environmental damage rather than every direct flamethrower hit or all area weapons. The trench’s area-resistance coefficient of 0.6 does not establish damage to the building or its occupants. Our advice is to check the garrison and specific attack method, without presenting artillery as a universal answer.
