Russian servicemen and former servicemen are marking Paratroopers Day.
August 2, the anniversary of the founding of the paratroops in 1935, is traditionally marked with veteran paratroopers parading through public parks in their signature berets and striped T-shirts.
In Moscow, events are held in Gorky Park.
According to city authorities, more than 3,000 police officers will be on duty in Moscow to keep order on a holiday often marred by excessive drinking and brawling.
Moscow's 103 public fountains will be operating as usual, despite the Paratroopers Day tradition of entering them and splashing around.
