The first Patriot emerged from the bloody battle on Tarawa during the Second World War.  Vincent Jeffries battled against legions of Japanese soldiers with an unearthly resilience, and his valiant actions rallied other Marines which helped turn the bloody tide of the battle.  After the American's success, Jeffries was sent back to the United States for medical attention.  He had suffered greatly, taking more than twenty bullets and numerous bayonet charges, but the young Kentucky Marine was still breathing.

After the War, Jeffries became known as Patriot and his war effort was covered in an issue of Time Magazine which catapulted him into the role of American Hero.  He remained in the Marines and attempted to remain the same down-to-earth man he had been before the War.  He eventually married and drifted into the background as more and more uberhumans emerged in the United States.  During the opening stages of America's involvement in the Vietnam War, Jeffries was killed which resulted in a surge in support for the War.  After the death of the first Patriot, the American military decided to pass the identity on to another soldier to maintain the reputation and the support Patriot had garnered.  This second Patriot was Captain Lindsay Grant.  While he never captured the widespread public support of his predecessor, Grant did serve the Army well.  He fought throughout the Vietnam War and then in several other conflicts during the 1980s and 1990s.  He was killed under suspicious circumstances during the liberation of Kuwait in 1991.  No body was recovered and although there was an investigation, no public record was issued.

Jeffries' grand-daughter Adrienne had, meanwhile, joined the Infantry (1st Division) and had fought in the Gulf War.  After the second Patriot's disappearance, Adrienne was approached by military intelligence and ordered to undergo scientific tests which triggered her latent ubergene.  She possessed similar powers to her grandfather and she was ordered to assume the mantle of Patriot, something she was proud to do.  She was transferred to the Devil Brigade where she worked her way up to the rank of Major.  The emergence of Major American as America's most popular government superhero led to a rather acrimonious confrontation between Major American and Patriot.  The argument, which involved a very short-lived brawl, was caught on television and played on most networks.  Patriot was reprimanded and has since refused to appear in public with Sanction and operates solely within the edicts of the American Army.

She is currently on deployment to Iraq where she has been working since 2006.

Adrienne grew up as an Army Brat, being the only child of an infantryman and the only grandchild of the first Patriot.  She takes her heritage very seriously and is an honourable and patriotic woman who exemplifies the traditions of the American Army.  She has gained the Army's respect as well, particularly through her frequent acts of valor in Iraq and before that, in Afghanistan.  She defends her men and women against any threat and will always be the last to leave a scene, never thinking of her own safety above that of her team.

She is well known for her loyalty and strength, although the on-air conflict with Major American still haunts her and media representatives often refer to it (probably in the hopes of a rematch).  Although she will never comment publicly on the argument she believes that Major American is an insult to the flag, and that he represents everything that is crass about Sanction and the populist uberhumans who say they serve the American nation.  Major American may have said something sexist or joked about the Army to trigger the conflict, but it is Patriot's deep seated belief that Major American is a phoney that led to that actual fight.

"The flag I wear into combat is the flag I will fight under until my death."

The third Patriot shares similar powers with those of her grandfather, the first Patriot.  She is resilient, in peak human form and has an uncanny ability to recover from most injuries.  In addition to these natural abilities which mark her beyond what is normally possible for humans, Patriot also wields the Patriot Gun which is a high powered handgun which is constantly being upgraded.  It is capable of shooting through most armour, but Patriot generally uses the less-lethal rubber bullets.  The Gun has various components which can be changed or modified.  The modifications are generally made in the combat field using components from her various pouches.

Adrienne Jeffries is a severe woman who doesn't smile often because there really isn't all that much to smile about, especially considering that America is at war.  She has shoulder-length light brown hair and blue eyes, although she isn't really considered feminine (possibly because of her obvious military bearing and steel gaze).  She is almost always in combat fatigues or the Patriot Armour which is composed of a hard plastic.  The chest plate is dark blue, the arms are red and the shoulder guards are white with the American flag emblazoned in the centre.  She generally wears fatigues over the top of her armoured legs as she is uncomfortable in the world of super heroes and doesn't want to lose touch with what she really is - a soldier.
