Vehicle:Monitor/Defense3

Monitors are lethal to board. Assuming the boarding pod bypasses the point defenses -- transport interdictors preclude attempts to simply beam troops onboard -- the boarders must contend with the polluted air, cramped internal spaces, onboard defenses, and sheer scale. All the numbers are in the Monitor's favor. These are city-sized spacecraft housing a city's worth of soldiers in a city's worth of rooms and corridors, and their decentralization ensures that any sabotage will only have minimal effect. Just... don't try to board a Monitor. You can't kill them that way.
