Where did the 539th US Army Artillery unit fight during World War 2?

Answer 1

The 539th Field Artillery Battalion did not receive credit for a campaign in WW2. It was recognized as an Occupation Force of Germany from 2 May until 31 Oct 1945. The only explanation for this is that they arrived too late to participate in a battle. So, they remained in Germany to help with re-settlement of civilians and maintain peace while the German army disarmed.

Reference: "Unit Citation and Campaign Participation Credit Register" Dept of Army Pamphlet 672-1 dated July 1961.

Sometimes units changed names or merged. Sometimes there were similar units with same number. I thought maybe this unit was re-designated as an Anti-Aircraft Weapons battalion. But the above reference only had one artillery unit with this number.
