ARMA 3 is an open-world, realism-based, military tactical shooter video game developed and published by Bohemia Interactive. It was released for Microsoft Windows in September 2013, and later announced for OS X and Linux in August 2015. ARMA 3’s storyline takes place in the mid-2030s during the fictional Operation Magnitude, a military operation launched by NATO forces fighting in Europe against “Eastern armies” referred to as Canton-Protocol Strategic Alliance Treaty (CSAT), led by a resurgent Iranian military with a coalition of other Middle Eastern and Asian nations, such as China.
The single-player campaign has the player take control of U.S. Army soldier Corporal Ben Kerry. During the campaign, the player will face everything from lone wolf infiltration missions to the commanding of large scale armored operations. The player will be able to choose different objectives and weaponry (such as UAVs, artillery, and air support) according to their play style.
ARMA 3 takes place on the Aegean-based islands of Altis and Stratis, and the South Pacific island of Tanoa. The islands feature photo-realistic terrain and water environments. Altis is the largest official terrain in the ARMA series with ground area covering approximately 270 square kilometres (100 sq mi). The smaller island, Stratis, expands over an area of 20 square kilometres (7.7 sq mi).
ARMA 3 is set in 2030s. The main singleplayer campaign, The East Wind, is set on the Mediterranean islands of Altis (based on Lemnos) and Stratis (based on Agios Efstratios). In 2026, a civil war erupts on the Republic of Altis and Stratis (Altis for short) following a coup d’etat by the nation’s armed forces, the Altis Armed Forces (AAF). In 2030, a ceasefire is declared. A loyalist rebel group, the Freedom and Independence Army (FIA), rejects the new military government and wages a guerilla campaign against the AAF. NATO peacekeeping forces are deployed to the region, establishing a US-led joint NATO-AAF peacekeeping force, Task Force Aegis.
Five years later, with NATO investment in the Aegean dwindling, the Canton-Protocol Strategic Alliance Treaty (CSAT), a military alliance of eastern hemisphere countries led by China and Iran, begins subsidizing the AAF and mobilizes its own forces in the Pacific. Facing political pressure to withdraw at the end of their peacekeeping mandate, NATO begins a drawdown of their expeditionary forces, causing tensions to rise between AAF and NATO forces.
The main player character of the singleplayer campaign is Corporal (later Sergeant) Ben Kerry, a US Army soldier deployed on Stratis. Players also play as Sergeant Conway during the prologue. Other major NATO characters include Staff Sergeant Adams, General Armstrong, as well as Combat Technology Research Group (a NATO spec ops group, CTRG for short) personnel Captain Scott Miller, and Miller’s second in command Lieutenant James. Major FIA characters include Kostas Stavrou, leader of northern FIA forces, and Nikos Panagopoulos, an FIA head.
In 2034, several months before the start of The East Wind, Staff Sergeant Adams and Sergeant Conway lead a small exercise for Task Force Aegis. During the exercise, an AAF patrol contacts Adams and requests assistance in response to an “incident”. Conway and Adams meets with the patrol and discover that they had killed a group of civilians, who they claim attacked them. Conway discovers an arms cache in the houses nearby, confirming that the civilians were FIA guerillas. Due to the ceasefire, the patrol’s use of lethal force becomes a tension point. Adams remarks that the FIA will no doubt retaliate.
