Callan Ward and key defender Phil Davis will co-captain GWS for a fifth-straight season, but Shane Mumford and Tom Scully have made way for four new additions to the group.
Reigning club champion Heath Shaw will again support Ward and Davis, who have shared the skipper's role since the Giants entered the competition in 2012.
Gun midfielders Stephen Coniglio, Dylan Shiel and Devon Smith, and defender Matt Buntine, all 22-year-old Giants' 'originals', have been given a spot on the leadership team for the first time.
"We've had young guys who have been doing leadership stuff for four years that they've been here and they're ready to step in," Ward said.
"We didn't want the group too large, and seven is the perfect number for us.
"We've got four fifth-year players who are terrific leaders, terrific men; that's what we're about at this football club, great men and great people so I think it's really good signs for us.
"They'll fill the shoes really well."
