The Earth Defense Force, abbreviated as EDF, is a large military organization and the main military force that fought against Mental's armies during the Mental War when they attacked Earth.
They serve as the main protagonistic faction throughout Serious Sam 3: BFE, Serious Sam 4 and Serious Sam: Siberian Mayhem.
Overview[]
The Earth Defense Force is a planetary-scale military force that was formed from the remnants of Earth's military forces. Most of the weapons and vehicles that are used by the EDF originally belonged to the U.S. Army, suggesting that the EDF formed from or was partially derived from this army branch.
Being Earth's main military force, the EDF are tasked with defending Earth and extraterrestrial colonies from alien attacks, such as Mental's Horde. However, after the colonies fell, only Earth remained, thus the planet serves as the military's last stronghold.[2] The Earth Defense Force army is massive, and included almost all of the forces on Earth and consisted of several thousand soldiers during the Tunguska Offensive.[3]
Elite squad[]
The EDF have a unit of well-known elite soldiers, called the Alien Artifact Acquisition, who specialize in collecting artifacts of extraterrestrial origin to assist the EDF during times of conflict.[2][4]
Role in the Mental War[]

When Mental had discovered mankind and the threat they could pose to his genocidal campaigns, he began sending wave after wave of his forces against the humans. He started with attacking the colonies in other star systems. Eventually, the colonies were wiped out and annihilated, and any survivors were forced to retreat back to Earth, which served as the Earth Defense Force's last stronghold.
Soon after, Mental tracked down the humans and came across Earth. As this planet harboured intelligent life, he began sending in a massive invasion force to attack. This initiated the Tunguska Offensive after a massive portal opened up in the Tunguska Plateau in Russia. After the portal became established, the enemy started to gradually take control of the continent and began spreading west towards Europe. Eventually, with the destruction of two small enemy portals thanks to the EDF's efforts, Mental's forces were eventually pushed back towards Tunguska. A massive battle took place which saw the destruction of the portal and the death of one of Mental's servants, Ugh-Zan VI.
However, while the Tunguska Offensive was a victory for the EDF, this was rather short-lived, as Mental took another approach and decided to attack the humans directly by sending in a large fleet of Alcor Class Warships approximately one year later.[5] The warships dealt severe infrastructal damage to Earth's cities, with settlements like Cairo being hit hard. The Earth Defense Force was eventually overwhelmed and had already used up most of their resources and supplies to repel Mental's forces.
Despite humanity's heavy losses, Mental's army had still taken many casualties, as the NETRISCA description for the Hatchling Arachnoid implies that Mental had to deploy younger and younger specimens to meet demands, with increasingly inferior equipment to replenish his losses. However, Mental's numbers ultimately proved to be too much for the EDF to handle. Humans were able to kill one of Mental's high-ranking servants, Ugh-Zan V, who had obliterated in Oslo.[6]
The fact that settlements like Cairo were completely abandoned suggested that the EDF was no longer capable of fighting Mental directly, and had to use more covert operations against him, such as deploying small squads of soldiers to locations to retrieve data for a new plan.[7]
Stopping Mental[]
Instead of fighting Mental directly, the Earth Defense Force created a plan to kill Mental in the past by using an ancient artifact of unknown origin called the Time-Lock. Believing that this device could be used to influence the future, this would allow the EDF to insert a group of soldiers know as Charlie Team into the past, and they would travel to Sirius and assassinate Mental while he was dealing with other matters.
However, the Earth Defense Force's headquarters, along with everybody (or most personnel, very likely every single person given how relentless and thorough Mental's army was) in it, were wiped out during the final days of the war, including Charlie Team, by a sneak attack on their headquarters by Mental. The destruction of their last headquarters and the Charlie Team signaled the end of the EDF. Not merely dissolving the EDF, but outright making it cease to exist completely. Despite Mental's best efforts to finish off humanity though, Sam Stone was able to successfully escape from Earth's inevitable destruction via the Time-Lock, which made him the last human on Earth and humanity's last hope.
Headquarters[]
Being a large military force, the Earth Defense Force has many bases or forward operating bases all around the world. Some of the more larger bases served as a temporary HQ. It is known they had two known headquarters; one was located in Italy and another one somewhere in Egypt. Some of their outposts were set up for relief efforts and to aid people in evacuating and establishing supply routes towards areas where they were needed.
During the later stages of the Mental War, most of the EDF's bases and outposts were abandoned or came under attack, and many military supplies and weaponry could be found in abundance in the bases or wherever EDF soldiers were stationed during the time.
Military technology[]
The EDF have access to a wide variety of advanced technology. They have managed to exploit some of the technology salvaged from Mental's forces, such as the techno-magical ammunition replenisher. High-ranking personnel use a radio or earpiece to communicate with one another and when they require assistance with something. The EDF also make use of alien technology or artifacts to assist their soldiers and to benefit mankind.

Transportation[]
The EDF uses many forms of standard ground and air transport, as well as several military spacecraft and enough equipment that protected holdings on other planets. As seen from EDF posters, they also used jet-powered attack aircraft. Most of the vehicles they have access to on Earth were originally owned by the United States Army or Marine Corps. They also utilize Russian Army vehicles.

They also have the technology to reverse-engineer weapons used by Mental's forces, such as the laser weapons used by Minor Bio-mechanoids or artillery used by Mental's forces.[8]
