The Argenta have a veteran corps of warriors, known as the Argenta Sentinelus. These warriors are some of the most elite the Argenta People have to offer.

There are different ranks in the Argenta Sentinelus, the legionaries (the most basic of soldiers), the sargentus (which command groups of 20 legionaries), the Capitatus (which command groups of 10 Sargentus), the Komanderiaii (which command groups of 100 Capitatus), and the Exultia (which command groups of 15 Komanderiaii).

These units all fall under direct command of the Kings of the Argenta, each region of Argenta having a specific King to rule over it. Each of the Kings elect an Emperor to rule broadly over all, and foresee military matters. The normal Argentan Military does not fall under these command structures, as these forces fall directly under the control of Argenta Royalty.

The average Argentan Warrior falls under command of the Argentan Senate. Argenta Sentinelus are highly rare, as the constant wars with the Pillager armies have devastated Argenta's Populations. Argenta Sentinelus Soldiers can be identified by their gray-blue armor, as opposed to standard Argenta who just wear gray armor.
