The gunship player here spent four Blastwing to:

• Kill one wind generator.
• Damage two mexes, draining energy and commander time.
• Temporarily block the construction of a mex.

At 4:40 the gunship player completed their land factory and was 430 metal ahead on the chart. This lead was due to faster expansion helped by a Wasp. The cost of the factory was mostly compensated for by a Tarantula.
