People have been wondering what the vanguard is. I believe that the vanguard are you, the guardian. I believe this for multiple reasons. First being the fact that on the back of the vanguard shirt is the fotc, fotc means forces of the city so it only makes sense for those two to go together. Also on Bungie.net it says waiting reports from the vanguard. This can only mean they were waiting for guardians to reliever information. Also, during the public event, the vanguard symbol appeared which means that guardians could participate. Lastly, the definition of vanguard fits perfectly with this hypothesis. Bungie day or now Bungie week is coming up soon so I am sure we will get the truth soon. What do you think the vanguard is???
