The command and control post

The route from the barrack area to the combat blocks is via a 1.2 kilometre-long tunnel known as the main gallery, which is served by a narrow-gauge electric railway. Just before the combat blocks and left off the main gallery, is the fort’s command and control post. This headquarters area comprised three separate commands – fort, infantry and artillery, although the majority of the facilities serve the latter. The role of the artillery headquarters was to gather information on enemy movements from the various observation posts on top of the combat and entrance blocks and then direct the most appropriate of the fort’s combat blocks to engage the threat. Time between first sighting and firing could be as little as three minutes.
