.EHB

From Emperor's Hammer Encyclopaedia Imperia

.EHB stands for "Emperor's Hammer Battle" and is a keyfile to an encrypted form of the .TIE file used by the X-Wing Series. While they do not run in the X-Wing Series games directly, they can be decrypted using the Emperor's Hammer Battle Launcher (EHBL). .EHB files are packed inside an .EHM file.
