 Tradition dictated that when AOCS graduates were commissioned, the first salute they received was from their former Marine Corps drill instructor (returned with a silver dollar handshake).When AOCS and OCS merged, the unified OCS program retained the Marine Corps tradition alongside Navy Recruit Division Commanders (RDC).This continuing Marine presence is the origin of the slogan "Navy owned, Marine Corps trained" and the distinctive blue "Bulldog" company guidons.
