have ribbons based on their regimental colours, worn crossed behind the cap badge and tucked in at the back. Wedge cap The wedge cap is the only headdress authorized for wear with Air Force ceremonial dress. It is also worn with Air Force service dress and flying clothing, but not with CADPAT (the beret is also authorized for wear with these orders of dress). A rifle green version, referred to as the field service cap, is worn by rifle regiments of the Royal Canadian Infantry Corps. Regulations Regulations for the wear of uniforms are contained in the CF publication Canadian Forces Dress Instructions. Amendments to dress regulations are issued through the office of the Vice Chief of the Defence Staff (VCDS), initially in the form of a CANFORGEN (Canadian Forces General) message, which is placed in the dress manual until an official publication amendment can be promulgated. Dress regulations may also be amplified, interpreted, or amended by the commanders of formations and units (depending on the commander's authority) through the issuing of Standing Orders (SOs), Ship's Standing Orders (SSO), Routine Orders (ROs), and Standard Operating Procedures (SOPs). This may include amplification where the regulations are unclear or are not mandatory; amendments or reversal of some existing regulations for special occasions or events; or the promulgation of regulations regarding the wear of traditional regimental articles (such as kilts).
