* Yellow Lantern Corps (aka Yellow Lanterns, Gold Lanterns, Sinestro Corps, F.E.A.R. Corps): Like the others on their side of the spectrum, those who bear the Yellow Light of Fear tend to have a bad reputation. Some of them deserve it, but those who join the Corps are expected to be, or become, better than that.

There was some debate over naming this Corps the 'Sinestro Corps' officially, as exceptions were made for the Star Sapphire Corps and the Indigo Tribe, but it was felt that this would be tempting fate too much. It didn't stop many comics fans, and some members, from nicknaming it the Sinestro Corps, though.

The Yellow Lantern Corps are one of only two Corps who have a complex hierarchy of ranks (that they actually pay attention to), in their case in the style of a military force (ironic, given that far more of them are cops, than are military). Rank insignia are displayed within the Lantern sigil, though depending on the individual 'uniform' style, they may be shown elsewhere, as well. Normally, this in on the upper sleeve for Enlisted and NCOs, and the collar for officers:

Rank 5:
OF-5 (Senior Commander) [eagle with Yellow Lantern sigil on its chest, wreathed]
OF-5 Commander [eagle with Yellow Lantern sigil on its chest]

Rank 4:
OF-3 (Vice Commander) [oak leaf, wreathed]
OF-3 Major [oak leaf]

Rank 3:
OF-2 Captain [two bars]
OF-1 Lieutenant [one bar]

Rank 2:
OR-5 (Sergeant Major) [three point-up chevrons over one rocker, with DC logo inside]
OR-5 (Staff Sergeant) [three point-up chevrons over one rocker]
OR-5 Sergeant [three point-up chevrons]

Rank 1:
OR-4 Corporal [two point-up chevrons]

Rank 0:
OR-2 Lantern [one point-up chevron]
OR-1 Recruit [no insignia]

Ranks in parentheses are positions, rather than official ranks, as the Yellow Lantern Corps is not large enough to really need so many ranks in general, but some regions have more Yellow Lanterns than others, and some Yellow Lanterns are more respected than others.

Lanterns who are also active, reserve, or retired members of military or police forces, or other uniformed government services, often have the same rank, or a bit higher, in the Corps. Those who are not part of such a service have ranks based on training, tests, experience, and the needs of the Corps - the latter can lead to some quite unexpected promotions, especially early on. It is somewhat more common though, for behavioral and trust issues to result in a Yellow Lantern having a lower rank than his or her prior service would indicate, as the Yellow Lantern Corps has, by necessity, rather more strict psychological standards than most police forces, and most other Lantern Corps.

Most Yellow rings can detect, encourage, and manipulate the fears in the minds of nearby individuals, or with great difficulty, even create them where none exist (causing an armed robber to briefly become afraid of his own gun, for example), though an effort of Will can block or end such effects.

Some Yellow rings cannot affect anything coloured Blue (or in a few cases, Green), or have difficulty doing so without the wielder performing some variety of mental gymnastics. Even those that are capable of affecting blue things, however, will have their constructs and other effects eroded by a sufficiently strong application of the Blue Light of Hope.

Since August 14, 2013, there have been, in effect, two Corps wielding the Yellow Light of Fear: the official Non-Government Organization chartered by Time-Warner/DC (the Yellow Lantern Corps), and a secret organization being gradually formed by subverting members of the NGO, and unaffiliated Yellow Lanterns (the Sinestro Corps). The latter force began due to an arrogant fool possessing both a Yellow power ring, and a knowledge of spirit-summoning, who summoned the thoughtform of Thaal Sinestro (comics version) to learn from him, and instead got himself possessed. The two Corps use the same rank scheme, for ease of infiltration, save that 'Sinestro' holds the rank of 'Supreme Commander' (OF-7, GURPS Rank 6) in his Corps.


* Green Lantern Corps (aka Green Lanterns, F-Sharp Bells, Willslingers): The most common variety of Lantern by far, and the colour with the largest ratio of members to Ringwielders of that colour.

The Green Lantern Corps are one of only two Corps who have a complex hierarchy of ranks (that they actually pay attention to), in their case based on a mix of modern police ranks, and Latin titles & ranks - the latter due to the use of 'Clarissi' and 'Illustres' (singular 'Illustris') in Blackest Night. Rank insignia are displayed within the Lantern sigil, though depending on the individual 'uniform' style, they may be shown elsewhere, as well or instead. Normally, this in on the upper sleeve for Decurions and below, and the collar for officers:

Rank 7:
OF-7 Clarissi [three stars]

Rank 6:
OF-6 Illustris [two stars]
OF-5 Chief Inspector [one star]

Rank 5:
OF-4 Inspector [eagle with Green Lantern sigil on its chest]

Rank 4:
OF-3 Deputy Inspector [oak leaf]

Rank 3:
OF-2 Centurion [two bars]
OF-1 Lieutenant [one bar]

Rank 2:
OR-6 Decurion [three point-down chevrons]

Rank 1:
OR-4 Senior Lantern [two point-down chevrons]

Rank 0:
OR-2 Lantern [no insignia]
OR-1 Cadet [no insignia, no Lantern badge]

Ranks are determined in much the same way as with Yellow Lanterns, though in many Sectors 'needs of the Corps' includes 'needing the highest-ranked Green Lantern to outrank the highest Yellow Lantern', or 'needing the handler of a Yellow Lantern to outrank that specific Yellow Lantern'. Where practical, the Sector may have all Green Lanterns outrank all Yellow Lanterns, though this is often cause for resentment among the F.E.A.R. Corps.

Lt. Col. Jordan Halley, USAF, ret. (a former officer of the Air Force Office of Special Investigations, who has never been a test pilot or fighter pilot), is the current Clarissi of the Green Lantern Corps. She got the job due to being both an excellent administrator, and a highly competent law-enforcement officer, not by being a particularly strong ring-wielder - powerwise, she's not much above average for a Green, and most likely got the ring due to her name. Notably, she is a highly skilled, precise, and imaginative ring-wielder, and her ring is not one with any of the weaknesses noted below.

Oddly, Green rings are able to absorb energy from Indigo rings, even if the Indigo wielder does not wish this.

Some Green rings cannot effect anything coloured Yellow, or have difficulty doing so without the wielder performing some variety of mental gymnastics. Others have a similar difficulty with things made of Wood, Gold, or Aluminium. None have more than one colour/material of weakness. Both Yellow and Red power rings are able to erode Green constructs and effects more easily than other Lights, though Green Lanterns who have mastered there own fear and/or rage are generally immune to this. A number of Green rings are vulnerable to sound waves in various ways, such as making constructs significantly smaller than intended.
