It will be detailed further in the OOC, but military equipment will be more advanced than current tech, while remaining grounded and avoiding energy-based weaponry and technology like flying cars, etc. In all honesty, it will borrow from similar universes such as Halo, Syndicate, and Dredd. Guns will still be ballistic, vehicles are either on-planet wheeled vehicles or off-planet transport vessels (there are no 'fighter ships', or similar personal-use space vessels), and armour will be tactical with modifications.
