A few years ago they did a military exercise where France, in a state of civil war/secession following a government bankruptcy, used its military to try and loot Swiss wealth.
French authorities were not amused.

But usually, the invading forces are color coded and not named with real life names. I remember doing one where from the west blue forces, from the north brown forces and from the east red forces were the enemies.
It's hard to come up with realistic military scenarios that involve invasions of foreign forces if you are a small landlocked country which is completely surrounded by friendly, democratic countries. :-)
Not a particularly far-fetched scenario, if you ask me. Except for the last part, coz there ain't enough money left to run a military organization.
