This man's army, this man's town

Posted by A. Kahrobaie on May 16, 2006

Is there anybody interested in and familiar with Dos Passos's "BIG MONEY"?
I can't understand the meaning of "man" in the following phrases:
1. "I'm fed up with this man's army, I guess."
2. " I was just wondering what a feller could do with himself in this man's town.
I appreciate your assistance.
