The HFFL forums have been open for about 10 days now. While the ranks were available to see on the forums first day, I haven’t showcased them here. So without further ado, here are what the ranks emblem look like and the name of each:
(Click to make graphic bigger)

These rank emblems and names closely follow the current U.S. Navy rank emblems.
Starting from the top left to right. Recruit being the lowest rank with no emblem.

The red striped emblems are Petty Officers, then the gold strips are chiefs, followed by gold bars for officers, then large bars with stars for Admirals. The last three are special ranks. VIP Admiral is just that. Someone within either 343 or one of their partners gets this rank. Note that there dis a capital “V” on the top star. Moderators get the same ranks but with an “M” instead of the “V”. And finally, the rank reserved for myself…yes, I know, but I am the owner and admin of the site. Fleet Admiral.

Come on over and join the forums and get in on a lot of Halo discussion. We talk about everything Halo, from the current and previous games; to Halo merchandise, including Halo Mega Bloks; to novels and comic books; and much more!
