RE:RE:Only in Castreaus woke Canada could this happen
The link you provided and picture are veterans wearing the Canadian Legion vest. The vests have various patches from unit served, deployments, other military patches (such as jump wings, legion branch) You don't need to be a biker to buy the vest just need to belong to the legion of your area and in good standing when you left the military.
I know many vets that have the vest and not one belongs to a gang nor do they pretend to do so. The vest is a symbol of their service and brotherhood as seen by the medals on those vests.
As for the uniform once one leaves the military they are no longer allowed to wear the uniform. As a veteran myself I would recommend doing some research befor posting on topics you seem not understand.
