Officers are taking part in city centre training exercises in order to deal with Commonwealth Games crowds.
Dozens of police - including a sniffer dog - were in Buchanan Street to test their skills.
For weeks Police Scotland has been training its officers to deal with the swarms of visitors who will flood Glasgow when the Games begin on July 23.
Part of their course involves putting their skills into practice in the city centre.
Police Scotland would not say how many officers are involved in the training.
A spokeswoman for Police Scotland said: "Police Scotland can confirm that the presence of police officers at Buchanan St today is in relation to one of many training events that are occurring in preparation for the Commonwealth Games.
"This is part of thorough preparation at all levels to ensure the public are kept safe during the Games."
