3. Military Arms are bound in the beginning to what the RL nation that you inhabit have.
That's the maximum at start so to speak. You can always have a weaker army of course.
Always assume that a restarted or new nation is lacking in organization and supplies for their armed forces and that the situation will improve over time as the new nation becomes more and more stable.
Some leeway in terms of equipment can be allowed as well to suit personal tastes. (You might prefer Centurion tanks to T-72 for example or MiG-21 to F4 Phantom etc.).
5. Expansionism is rampant.
And occasionally frowned upon when players cannot keep IC and OOC conflicts apart.
