Adolf Galland may have shared a name with a famous warrior, but he was no fighter. If anything, he was a little coward that compromised on just about everything to calm those fears. He didn't live in the port city proper because of the pollution, crime, and crowds - but wouldn't move to a little town because of the medical care available in the metropolis. Out of the fear of being stranded, he had his own car, despite the costs involved, and maintained his own bio-fuel reactor to make sure it would always run. He even joined a gun club and acquired a Kleiner Waffenschein. (Firearms carry permit.)
What many before the event would have defined as near mental illness - or at least a bit strange - had made him the center of a little survivors community near Emden. Even then, it was more about fearing the disapproval of his neighbors, than stepping up to save the community from the new scourge.
Even if he was the unofficial leader, he would still take turns along the river with binoculars looking for boats. What he would do if he actually spotted a KCA ship was unknown, but then again - there wasn't much to do. They couldn't very well fight back against an armed warship and actual marines, and a scorched earth policy would leave them worse off than if they just gave the stuff away. Hiring a free company would require having something to trade that couldn't just be looted from the city a few kilometers away.
