Authorities in Germany's capital Berlin have banned local performers from wearing US army uniforms at Checkpoint Charlie, the iconic Cold War crossing between the east and west of the city.
They said the actors exploited tourists by demanding money for photos at the attraction.
The checkpoint was designated as the only crossing for foreigners and allied troops when the city was divided.
East and West Berlin were separated by the Berlin Wall from 1961-89.
The ban comes as Germany celebrates 30 years since the fall of the Wall, built to prevent residents of Communist East Germany from fleeing to the West.
Authorities in the city's central Mitte district revoked the performing licence of a group of performers known as Dance Factory, the Bild newspaper reported on Monday.
The actors say they only accept voluntary contributions for photos and souvenir passport stamps.
But an undercover operation by police posing as tourists allegedly found that the performers were demanding a €4 ($4.5; £3.5) fee and verbally abusing those who refused to pay.
Groups that want to charge money for such performances in Berlin require a special permit.
People impersonating US soldiers have been at Checkpoint Charlie for nearly 20 years, working in rotation to pose with tourists.
But many Berliners are unhappy about the "Disneyfication" of the site, where fake Soviet Red Army fur hats, gas masks and pieces of the Berlin Wall can be found for sale.
The move echoes a decision from 2015, when authorities in the Italian capital Rome banned people impersonating ancient Roman soldiers, along with ticket touts and bicycle rickshaw drivers, from the Colosseum, Forum and other major tourist sites.
