Centinela is a word from the Italian language, specifically from the Italian voice “sentinella”, which derives from the verb “sentire”, which means “to hear”. Sentinel is understood to be that soldier, military officer or officer who is in charge of guarding or guarding the place assigned to him; In other words, it is the individual who guards, supervises and defends a specific position. The sentry is arranged in a given observation post with the purpose of defending at all costs a position, person, facility or sector, and if any inconvenience arises, he is in charge of transmitting an encrypted message or by means of a password to the rest of the team. so that they are attentive to any eventuality.
According to Spanish military legislation, they describe the sentry as the soldiers of the guard who remain firm in their posts or those who carry out short surveillance tours, either alone or in groups, with their face always outside, and who also has license to use your weapon in any defense situation for the orders that are given and protection of your post. This differentiates the sentries from the simple vigilantes, who fulfill functions of the internal regime, and who are only authorized to use their weapons in self-defense. Of course, other military laws have substantially similar regulations.
The action carried out by a sentry is of the utmost importance, so that the security of the group or sector to be monitored depends on it; For this reason, the norms of action of a sentry are established in a rigid and highly specific manner in all ordinances and military norms.
