A seagun is a manmade concrete “island” with a massive automatic gun on top. During peacetimes, the guns are turned off, but as soon as Axolotlia ends up at war, the seaguns are powered on and will shoot enemy targets.
They are named the same as naval military bases, but with a 1s instead of just 1, the s is for seagun. (1s-Ca-5)
Axolotlia has 107 seaguns scattered around the islands and even in lakes. Mostly near large coastal cities. (Axoton, Lucinia, Grentville/Grenton, etc.), and strategic waters (like the entrances to the Grent Sea.)
The first seagun was set up just after the Canadian Invasion peace treaty.
They also act as stations for drones and speedboats.
