Ben Mowen will captain the Brumbies in this season's Super Rugby competition once again ahead of Wallabies David Pocock and Stephen Moore.
Pocock, who has captained the Wallabies, joined the Brumbies in the off-season from the Western Force, where he also led the Perth-based Super Rugby side.
Coach Jake White said No.8 Mowen had proven himself to be a valuable leader of the Brumbies.
"Ben's proven above and beyond that he is a quality leader and the right man to be captain of this team into the future," White said.
"There were numerous times through the (last) season that his leadership proved the difference for the Brumbies and it's a pleasure to have him back in the same position for 2013."
"Ben has not only my support but the entire playing group and the ACT community are with him too. He is an asset to the team and will work nicely with the vice-captains, David (Pocock), Stephen (Moore) and Christian (Lealiifano)," added White.
Now in his second season as vice-captain of the Brumbies, Moore provided leadership and guidance for a young and inexperienced pack in 2012. Having led the side as skipper on two occasions (2011 v Stormers; 2012 v Lions), Moore is one of the Brumbies most consistent performers.
Following a breakout year in 2012, Lealiifano has been handed the vice-captain's badge as he makes a return from a broken ankle.
Lealiifano was one of the form players of the Australian conference in 2012 before suffering the break against the Waratahs, 10 games into the season.
Rounding out the trio of vice captains for 2013 is Pocock, who at 24 already boasts a wealth of leadership experience. With 69 Super Rugby caps and 45 Tests, Pocock is one of Australia's most respected rugby brains and talented players.
