Celtic skipper Brown will lead out the team for the first time ahead of Wednesday night's friendly against Estonia at Pittodrie.
"He already knows what it's like to be a captain with pressure and that made him favourite," Strachan told a press conference in Aberdeen.
Gary Caldwell and Kenny Miller have shared captaincy duties in the absence of Darren Fletcher, who is battling a chronic bowel condition, but Caldwell has returned to Wigan with an injury and 33-year-old Miller is unlikely to start as the Vancouver Whitecaps striker is in the midst of his close season.
