It is the structure by which you bring your problems and/or questions to higher ranking members.

No. It depends on your department/squad and department/squad position.

The basic CoC structure is as follows:

• Another department staff/squad member or the forums
• Department/Squad XO
• Department/Squad CO
• Division (BF3 or EVE) XO (if issue is squad related)
• Division (BF3 or EVE) CO (if issue is squad related)
• High Command member
• Clan XO
• Clan CO

You are expected to address senior officers and staff members as sir or ma'am or their title/rank.
