We have begun migration of most wikis to our new host, Amazon Web Services. All but the top 100 wikis are in read-only mode until the migration is complete. Estimated completion: End of Week.
The builds in Heroes & Generals are named after various generals following the alphabet. This is because it is easier to remember that you are playing a build named 'Rommel' or 'Patton' than 'Build 98765'.
