Nameplate

A Nameplate is a means of displaying the name of a person or product, and are often identified by rectangular strips, although they can be found in other shapes as well.

The Diamond Dogs and various other Private Forces active during the 1980s utilized nameplates for their various bases, including the main operating base of the former.

Behind the scenes
Nameplates were a concept introduced in the Version 1.07 update for Metal Gear Solid V: The Phantom Pain, as a means of making the player's Mother Base a bit more distinct. It can be found on the iDroid's Mother Base menu under the Customization submenu. They can be purchased via Event Points, which are also introduced in the same update.

The following are available/known:

The Quiet, D-Dog, D-Horse, Miller, Ocelot, Skull Face, and Man on Fire nameplates require the player to successfully infiltrate a FOB armed with a Defender during the Event Period, with it being necessary to infiltrate once, 10, 30, and 100 times depending on the nameplate type (normal, bronze, silver, and gold, respectively). The Snake nameplates, likewise, requires that the player gain top rankings in Event Points, with normal requiring top 501-1000, bronze requiring top 101-500, silver requiring top 11-100, and gold requiring top 1-10. On a related note, the Snake nameplates are the only nameplate sets to require the direct involvement of the FOB event mission in the event period to unlock, as the others, while released during specific FOB event periods, require that the player do security challenges instead of the actual FOB event missions to access.

In the initial release for the nameplates, not counting the Snake nameplate set, they also were released with an emblem matching the character in the nameplate. The only exceptions were the Miller nameplate, which had the Buddy Emblem: D-Walker being released instead of an actual emblem for Miller, and the Man on Fire, who also had an emblem of Third Child released alongside an emblem of the Man on Fire himself (the latter being a reference to their partnership in the game).

The nameplates also have a varying logo on each of them. The normal version has no logo on it, the Bronze version has the Militaires Sans Frontières logo, the Silver version has the Diamond Dogs logo, and the Gold version has the initial Outer Heaven logo.

In some FOBs between January 5 and January 12, there was at least one player spotted with a Gold-colored Skull Face nameplate, implying that he was going to be in a series of nameplates and that there were going to be more nameplates besides Snake, Quiet, D-Dog, and D-Horse. Leaked data confirmed as much and also revealed that there would be nameplates for Skull Face, Ocelot, Miller, and the Man on Fire.

Teaser images for the Event Point prizes implied that the nameplates would have cost 30000 Event Points, although in the final version, they cost 800 EP. Something similar was also observed with the other prize items.
