How do you know if they have Militray units?
Thats kind of funny in a historical sense.
Sea Captain to Enemy ship Captain: "What does your fleet carry?"
Enemy Sea Captain: "3000 of our most horrible, violent, toughest warriors ready to kill, slaughter, burn and plunder your cities"
Sea Captain: "Oh you should said mate. Pass right through."
And in another scenario
Sea Captain "What does your fleet carry?"
Enemy Sea Captain “Nothing really just a diplomat for peace talks."
Sea Captain "Sink the bastards! Quick!"
