There are eight platoons of House Io Troops (Six Organic Citizens platoons plus two siren Platoons) One more is acting as spec ops trying to blunt the Mandalorian offense elsewhere
One Platoon is at the exterior firing at everything that's shooting at them the rest are on the interior, one platoon guarding the main Generator itself, the rest are defending choke points that lead to it. Lyssa is where Kranak is.
My forces are mainly using the Assault Radiation Blaster as a key weapon will provide a link to this weapon if you like to understand its Effects,
