January

• January 5: Nathan Hale is promoted to Lieutenant.

March

• March 22: Sergeant Benjamin Warner is captured and served 30 days in stockade for "absence without leave" and attempting to make contact with his family.
• March 24: Dr. Fyodor Malikov writes a letter to Major Richard Blake briefing on three unusual artifacts known as "gray tech".
• March 30: Major Blake sent a written proposal to President Harvey McCullen of forming a "new special forces detachment" known as Specter that is specifically tasked in infiltrating Chimeran held territories and recovering gray tech.

April

• April 6: The Chimera invades Africa. Despite the warm African temperature, the Chimera have evolved newer strains of the hybrid virus along with more advanced heat radiation implants that allow their troops to withstand much higher temperatures.
• April 11: Nathan Hale is awarded the Silver Star for the successful retrieval of eighteen stranded civilians inside gray territory formerly known as Wisconsin.
• April 19: Specter Team infiltrate Chimera-occupied Chicago and prevent the Chimera from launching a full-scale ground assault on the northeast section of the Liberty Defense Perimeter, during Operation Shadow Strike.
• April 21: SRPA Recon Team X-Ray infiltrate the Chicago Tower. After accessing one of the tower's control stations by using the Malikov Cipher, they learned that the tower is linked to seven other towers, six of which were previously unknown.
• April 22: The Chimeran threat in Chicago is largely contained. Specter Team had decimated the Chimeran command structure, seized key strategic locations, eliminating much of the Chimeran infrastructure in the city and result their first victory against Daedalus. Chicago still remained as gray territory.
• April 23: President McCullen repealed Noah Grace's long-standing ban on all immigration into the United States.
• April 24: Africa is finally overrun by the Chimera as over 170,000 African civilians are evacuated from the Northern and Western coasts of the continent by British forces.
• April 28: President McCullen announced a new executive initiative in which 150,000 selected American citizens will be transported to the Hawaiian islands where they will continue to live indefinitely. Some reporters dubbed the initiative "Operation Aloha."
• April 30: President McCullen issues evacuation orders to major cities in the United States.

May

• May 3: Intelligence analysts at SRPA 3 discovered that the Chimera are constructing a 300-foot-tall enclosure surrounding Wrigley Field inside Chicago. SRPA, however see it as an insignificant threat. The enclosure is implicated to be the birthplace of the Leviathan.
• May 15: American citizens start to be receiving authorization papers for evacuation to the Liberty Defense Perimeter based on lottery.

July

• The V7 Splicer receives a green light for active use.
• July 1: 150,000 selected American citizens are transported to Hawaii.
• July 23: A surprise Chimeran aerial attack hit Orick, California; catching American military forces off guard. On the same day, massive spire attacks hit Florida and Georgia, prompting President McCullen to declare the entire southeast coast a Gray Zone.
• July 23: A group of survivors in Savannah, Georgia takes shelter in the Telfair Museum and sent a distress signal over ham radio. 
• July 24: President McCullen orders all remaining U.S. citizens living in outer states to evacuate their homes and move within the Liberty Defense Perimeter, which is nearing completion. He commissions emergency construction of an additional 50 protection camps within the LDP.
• July 25: Sergeant Benjamin Warner of Echo Team executed Operation Iron Hand that successfully rescued 73 citizens from Savannah, Georgia.
• July 27: Specter Team initiate Operation Green Eagle in order to destroy the Chimeran command structure in Orick.
• July 30: U.S. forces in Panama City spotted four Chimeran airships that are traveling toward Columbia. In the ensuing three days the airships blanketed South America with wave after wave of spire missiles.

August

• August 1: SRPA learned Orick possessed large quantities of gray tech.
• August 5: Operation Green Eagle results in a decisive victory for SRPA. Specter Team inflicted heavy casualties on the Chimeran command structure in Orick. Without a command structure, Chimeran forces are unable to produce enough troop quantities in the area towards large population targets. The Chimera's attack on Orick appears to have been backfired as Specter Team succeeded in recovering Grey Tech components in the area.
• August 7: SRPA intelligence analyzed that the Chimeran command structure has become far more organized and hierarchical in the past months, without their dependency on the Angels.
• August 9:
  • Reconnaissance teams spotted two very large Chimeran aerial battleships approximately three miles off the coast of San Francisco. The vessels did not attempt to or further approach the city. It is suspected that the Chimera may have been testing the range of San Francisco's anti-aircraft batteries. This marks the fifth sighting of these vessels.
  • Due to the influx of refugees from around the world and the shortage of food and supplies, Australia has rapidly escalated into civil war.
• August 10: Dr. Fyodor Malikov notes in his journal that after testing the isotopes of the gray tech it reveals that its materials were not of terrestrial origins and believed to be created by unknown beings who had contacted with the Chimera.
• August 11: President McCullen reiterated his open border policies to refugees heralding from Gray Zone countries in response to the Chimera's Spire attacks on South America.
• August 12: Dr. Richard P. Feynman at SRPA 7 describes the surprising results of the gray tech components and deduced that the technologies were meant to form a larger component as if it were a puzzle. He, however, notes the question as to why the gray tech were separated around the world in the first place.
• August 14: The Liberty Defense Perimeter is finally completed.

September

• September 14: In the past two months spire attacks has been increasing on the coasts of the United States as large sections of all coastal states are now gray zones, and the Chimera continue to build infrastructure at these locations. SRPA intelligence believes that the Chimera's unusual display of military prowess and centering their attacks on least defended high populations areas suggest that the Chimeran strategy is heavily influenced and commanded by Daedalus.
• September 25: The U.S. Army list Aaron Hawthorne as killed in action before he's reclaimed by SRPA.
• September 27: Treatment of Inhibitor Stage 5 for Aaron Hawthorne has been authorized.
• September 28: Aaron Hawthorne is recruited into the Sentinel Program.

October

• October 1: Aaron Hawthorne is transferred to Echo Team.
• October 8: Sentinel Team Echo successfully infiltrated and destroyed an Chimeran factory that had been constructing fighter aircraft during Operation Kodiak. One unexpected outcome of the operation is the acquisition of a disassembled Chimeran aircraft.

November

• November 2: Aaron Hawthorne is awarded the SRPA Gold Cross for exemplary service during Operation Charon.
• November 10: Joseph Capelli is demoted from Sergeant to Corporal and is sentenced to three months inactive status.
• November 11: Nathan Hale planned and executed Operation Frozen Fortress.

December

• December 7: The SRPA initiates Operation Allied Shield to protect Axbridge, which conduct into recovered gray tech and Chimeran nuclear technology, from a Chimeran attack.
• December 8: SRPA Team Alpha is lost when attempting to infiltrate an enemy command outpost in Bend, Oregon.
• December 9: Operation Allied Shield continues to be successful, but the Chimera continue to send in reinforcement via dropships to Axbridge. Colonel Rachel Parker provides schematics of a nuclear reactor configuration to SRPA, which they send the data to SRPA NT.
• December 12: The Chimeran threat in Axbridge is largely contained by Specter Team. The Chimera fails to divert British forces from the European mainland as the continental towers are left vulnerable for Allied forces.
• December 13: President McCullen authorized additional funding for gray tech research under Project Prometheus. Dr. Julia Cathcart at SRPA 7 proposes her theories about the gray tech components being part of a powerful, ancient weapon dubbed as the "Prometheus Weapon".
• December 14: Chimeran forces retake Bracknell, formerly one of the largest Chimeran bases of power, in an attempt to launch a broader attack across all of England..
• December 18: SRPA Team Specter is dispatched to contain the Chimera in Bracknell in Operation Viper Pit.
• December 21: Echo Team's leader, Lt. Hank Leavitt, is killed while attempting to destroy a Stalker production facility in Raleigh, North Carolina. Nathan Hale succeeds as leader of Echo Team.
• December 21: Dr. Julia Cathcart writes in her journal describing about the remarkable results of experimenting the gray tech components.
• December 22: SRPA analyzed the increasing casualties from Sentinel teams and their requirement for more advanced forms of inhibitor treatments to keep the Chimeran virus in their bodies in check.
• December 23: Colonel Rachel Parker advised all Allied forces not to attack the Cloven as they never appear to attack humans, unless they are attacked first. 
• December 24: Outside of Axbridge, SRPA recon teams discovered a destroyed drone construction factory with all the Chimera inside being killed and mutilated or partially eaten. The power cores in the equipment had been stripped throughout the facility. Also, that was discovered are the bodies of four Titan Overseers that were found with their hearts carved out and stacked on the floor. Near the hearts, scrawled in Chimeran blood, were words written in Russian, which translated to: "the angels sleep". The Cloven are at fault for the aforementioned actions. SRPA analysts doesn't perceive this as a threat to Specter Team or SRPA's salvage teams, but recon teams are ordered to continue to monitor the facility as a precaution.
• December 24: In a research laboratory in London, a female Cloven escaped from her cell and killed 14 British soldiers. One of the surviving guards claims that the prisoner "became invisible" and was shot "forty or fifty" times before escaping.
• December 25: In response to the laboratory incident in London, Colonel Rachel Parker issued a warning to military personnel to be exceedingly cautious of Cloven. She further requests that all Allied forces not to attempt to engage or hunt the Cloven as the creatures are not openly hostile toward humans unless provoked.
• December 27: The Chimeran threat in Bracknell is largely contained. While the Chimera still has command units in the area, they have been unable to establish increased infrastructure or sufficient troop numbers to launch an offensive beyond Bracknell.
• December 29: Dr. Richard Feynman writes in his journal that a recent experiment with the gray tech components reveals that the components themselves applies quantum electrodynamics to communicate with other gray tech components from long distances.
• December 31: British and Maquis forces discovered a conversion center in Hamburg, Germany where all the Chimera in the facility had been killed. Close inspections revealed that the Chimera had been killed with short, bladed weapons and many of their bodies were mutilated and eaten.
• December 31: Sentinel Team Delta led an assault on a Chimeran communications array in Montana but during the assault lost three of their members.
