F.O.E. (Fuerzas de Operaciones Especiales = Special Operation Forces) , at the beginning of the comic the FOE soldiers were called S.O.D or special operation division, which was later changed by their original Spanish acronym... which way more cool xd.

there's a small description of what the FOE represent in the Derideal World.

This page was included in the Chapter 0 to 4 PDF edition that was available for download on my tumblr long time ago.

The text might have some errors, but it was mostly because I didn't revised it before release xd.

FOE soldiers are part of my webcomic's universe - Derideal: http://projectprime.org/derideal/archive.php

if anyone is interested on the pdf compilation, let me know and I'll search for the file, there must be somewhere on the internet xd
