In the global game I just played, the French North African infantry put up a defence in Tunisia, and held it for 5 turns. The French Mediterranean fleet exited through the Suez Canal and helped put up a fleet blockade, passively protecting India from a rampaging Japan. The French unit in Syria went down to Trans-Jordan, then back up as Egypt fell and Germany managed to march through and grab Iraq. Further south, the French Central African unit marched east to act as a road block for the Italians, and was eventually killed.
It was a wild game.
