Blockhouse

Overview
The Blockhouse functions as an upgraded Pillbox, and can grant a large advantage to protecting a player's Outpost from unwelcome visitors. As with the other turret-like defenses, it has a direct line of fire, meaning that it cannot hit any unit is that is placed behind blocking units.

Building a Blockhouse is mandatory for the mission, Some Men Left Behind.

Trivia

 * This defense structure was probably based on the German fortress known to the allies as the "Block House" which was designed to launch V-2 rockets at England.
