Shielded Siege assault bot. Armed with a high-intensity laser. Can repair and reclaim Mass.
Time is 3,600 build points divided by build power. Drain is mass and energy per second while it is building, so more build power finishes sooner and costs the same total, but pulls harder on the economy.
Reclaims and repairs, which no other T3 assault unit does. A push of these does not need engineers following it to clear wrecks or patch the front line, and it carries a personal shield on top of its 3600 health.
