Hello Tygers!
Here is a spreadsheet showing your Heavy Fighting authorization status. Understand that it will always be a month behind as that is just how the update process works so plan accordingly. If you are within four months of your authorization expiring, DO NOT WAIT! Download the current Authorization form (posted on this site under Marshals) and get it done. If you have any questions send an email to the EK Armored Combat marshal or the EK Mistress of the Lists.
