I have an emblem on my soldier that I really like and I would like to use it a slightly altered version for my platoon. Can I somehow easily copy the emblem over so I can then make those slight adjustments? I really would not like to have to create the whole emblem again.
Yes you can.
You have to follow these steps to export your emblem:
Exporting your emblem
Once you have your emblem copied, bring up your platoon (you must be platoon leader (afaik) to edit the platoon's emblem). Navigate to the create a new emblem page and open the console again. Simply paste in that code you previously copied and save.
