Since this thread has gotten quite long since some of my original answers, I wanted to follow back with some some of the FAQ answers:
I connected my account, but I haven't received my items:
Please restart your client, they will then appear.
Id.ME doesn't seem to be working:
Due to the large amounts of traffic being directed to their site, they may have periodic outages. Please try again in 5-10 minutes.
What about non-USA veterans and military members:
Currently, with keeping mind on your information security, ID.ME only serves USA military members. We will keep an eye on other systems for verifying military members for other nations in a secure fashion. We hope to be able to offer this program for other nations in the future.
Why should I trust ID.ME / Is ID.ME secure:
While you should always do your own research before using any online system/website, ID.ME is affiliated with the US Government and has a strict level of security. This information is detailed on their website. ID.ME does not pass on any of your private information (SSN / DD214s / Etc) onto Wargaming, it only confirms veteran status for our systems.
These rewards aren't the best, what gives:
With this launch we wanted to keep rewards small to begin with, with the idea that these could be expanded upon on in the future.
We once again, thank all of our Military members across all branches and nations for their service. We are pleased so far with the successful launch of this initiative and hope to work even closer with our Veterans in the future.
