This section addressed the various other Military Systems that are currently in service and/or available around the world. Extensive work has been put into the entire section to include as much systems as possible, but not all variants are included. Variants are expected to be active, but if used the player will have to point this out. Every unit listed also has an indication if it is in production or not. If a unit is not in production it will be able to restart production for this unit again, however the player will have to take into account a possibly increased unit price (as the one mentioned is outdated) and costs to ensure that the production lines are opened again. 

Nations that at the moment do not have the capability to construct these type of weapon systems, cannot obtain a production license for systems, as they lack the facilities to construct them. A player should first ensure his nation is capable of producing the systems, before he can work out a license agreement with another nation.
