If worn by a female character, the T-45d pauldron will be upright rather than folded down.It is also one of the heaviest medium armors at a weight of 35 pounds, making it as heavy as Gannon family Tesla armor.As of patch 1.4.0.525, they are often worn by legionary assassins.

Normally the helmet is only worn by Aurelius of Phoenix and by the Legion centurions at the last stages of the game.

This is considered to be one of the rarest non-unique armors in the game, as there are only two locations before the final battle of Hoover Dam.

Only obtainable if the Legion is nuked during the quest The Apocalypse.

Dry Wells - Gaius Magnus is wearing the helmet.

Full sets can be found on legionary assassins as of patch 1.4.0.525.

The Legion centurions during the battle of Hoover Dam wear the body armor, and sometimes wear the helmet as well.

One can then loot his body for the armor afterward.

Releasing the radioactive barrels in the quest Eye for an Eye will also kill him.

Since BOS armor requires training, it's useless to the player character at the beginning of the game, but Aurelius can equip it. One can pickpocket his armor very early in the game by reverse-pickpocketing a fully repaired Brotherhood of Steel armor on him found on dead BOS soldiers in the wasteland.

Cottonwood Cove - Aurelius of Phoenix is wearing a set.

Camp McCarran - Silus is wearing the body part.

Caesar's Legion safehouse - A full set can be found if patch 1.2.0.31x is installed.Shin guards and the boots from combat armor.

Left forearm and hip plates from NCR Ranger patrol armor.

Right pauldron and forearm of a suit of T-45d power armor.

Helmet of a super mutant brute, polished and with a centurion's frill.

The armor is composed of other pieces of armor taken from that of the wearer's defeated opponents in combat. The Legion centurion armor is by far the strongest suit of armor available to Caesar's Legion, with a full set of both armor and helmet providing a Damage Threshold of 23, only 1 less point than a full set of the famous NCR Ranger combat armor.
