On July 28th, Austro-Hungarian forces began a general invasion of Serbia. Having extensively planned for this operation previously, with most officers having been taught Simple Danubian, and with a great stockpile of prepared supplies, it was a decisive victory. By the end of September, the country had been fully occupied, and only irregulars continued the fight for Serbia. Austro-Hungarian armies linked up with those of Bulgaria and the Ottomans, beginning a joint invasion of Greece, to dislodge Entente ships in the region and threaten Egypt. The Romanians, which had entered the war on the get-go, proved far more resistance with Russian reinforcements, but were eventually pushed back. By November of 1915, the Balkans were firmly in control of the Central Powers.

Somewhat further to the north, the Italians managed to push the French in the extremely bloody Battle of the Alps, though its colonial holdings were lost. Furthermore, on the border between the Ottoman levant and the British colony of Egypt, combat began to unfold.

The M-29 "Davy Crockett" is an novel American weapons system which entered service in the mid-1960s. It is a simple spigot recoilless gun firing a rather oversized egg-shaped shell at up to 2km away (for the 120mm M-28) or 4km away (for the 155mm M-29). What makes this weapon special is the W54 plutonium-compression fission warhead with a blast yield of 20t of TNT it will propel towards the enemy, delivering a deadly dose of radiation in a radius of 400m. Though inaccurate, it is a nuclear weapon, and does not require much precision. NATO troops stationed in Europe are equipped with Davy Crockett launchers. Like all nuclear weapons, it is closely monitored by every government agency in the planet, and not easy to find in Oceanyka's black market. Reports of W54 warhead or Davy Crockett launcher trafficking will likely result in a FED raid. 

On June 5th, 1916, Arab irregulars attacked the city of Medina under the orders of Hussein bin Ali, the Sharif of Mecca. This offensive operation was the first in a series of events that would stretch out of World War I, the Arab Revolt. In the months prior he had contacted representatives from the British Empire, who had promised aid in the form of gold, weapons and ammunition if the Arabs joined them against the Ottoman Empire. Many prominent leaders in Istambul were supporters of a radical Turkish-nationalist wing in the Ottoman government, and the state was undergoing a process of "turkification" which greatly angered its minorities, including the Arabs. Though that action was unsuccessful, five days later another group of irregulars attacked Mecca, putting the city under siege. With the aid of British regular troops from Egypt, Mecca was seized on July. Ottoman artillery fire had greatly damaged the holy city, an act which Hussein capitalised on to rally Arabia's devout population. British high command sent a number of officers to assist the Arabs with contemporary military tactics and strategy, as well as to act as liasons and information-gatherers. The most famous and influential of these was Captain Thomas Edward Lawrence, whose friendship with the revolt's leaders and knowledge on irregular warfare helped shape the Middle East's borders.

Medina and its railway were abandoned early in the revolt, as it became clear that British troops rampaging through Palestine would soon cut them off. The real breakthrough occurred when British forces seized Baghdad in February of 1917. As they kept pushing north, and it became clear that the Entente would likely lose this war, British high command authorised one last plan of revenge. On September 27th, 1917, and with full recognition from all remaining Entente nations, Sharif Hussein bin Ali proclaimed the Hejaz Caliphate, challenging the Ottoman claim to that title on the basis of descending from the Hashemite family (direct descendands of Muhammad) and controlling the three holiest cities in Islam. By this time, the Istambul government was collapsing from Armenian, Greek, Assyrian and Kurdish insurrections, despite genocidal campaigns against these groups. Largely with American weapons and British officers, the Regular Arab Army was established, mostly under the command of Hussein's son Faisal, who had T. E. Lawrence as his right hand.

In November of 1918, with only Britanny and the surrounding regions holding out against German attacks, and the Royal Navy decimated, an armistice was signed. Entente troops in the Middle-East, however, did not surrender their arms as the terms dictated, they simply handed them over to their insurrectionist allies and then gave themselves up. Thousands of French, Oceanykan, American and British volunteers chose to remain with the Regular Arab Army or similar movements, adopting local-sounding names (including most infamously T. E. Lawrence). They held a line from Adana, though Kayseri, to Trabzon and were recruiting every able-bodied male for an attack on Ankara.

This attack began on March of 1919, with over 240,000 deserters, conscripts, guerillas, irregulars and tribal fighters racing for the Ottoman Empire's second largest city. Istambul's government tasked Mustafa Kemal Ataturk with stopping them, granting him command of the best-equipped and most capable troops in the Ottoman Army, a mission which he succesfully accomplished at the Battle of the Salty Lakes. Discontent in the Turkish population had reached a boiling point, and protests erupted demanding peace with the other nationalities of the Empire, which were sure to begin performing crimes against humanity against the Turks for actions such as the Armenian, Assyrian, Kurdish and Greek genocides which Ottoman troops had carried out during World War I. When the Turkish Revolution broke out, Ataturk's Ankara-based forces immediately sought a ceasefire with the insurrectionists to protect his rear, promising independence and a stop to all massacres, deportations and death marches. The rebels agreed, thus peace was finally achieved on May 8th.

The Casava Repeater is perhaps the deadliest weapon wielded by the Precursors in Earth. It is an enormous weapon which even the Ancient Armoured Core, its bipedal compliment, has trouble carrying around. Though fully automtic, it has two firing modes. When in "Lance" mode, the particle beam created will have a diametre of 2m, erasing anything at a very considerable distance, likely able to hit objects up in the stratosphere. However, when in "Sword" mode, the particle beam will extend out on a significantly shorter ranged cone, which is able to hit a much larger area in front of the mecha with deadly high-speed radiation. 

Though it has numerous native names, that given to it by British colonists stayed. The shitchicken is a bird half a metre tall, which clucks much like an actual chicken. Upon arriving, said colonists believed that the locals had somehow tamed the common chicken, and it had readapted to live in the wild. Unfortunately, this fantasy ended when the first British explorer was eaten by a pack of carnivorous shitchickens. They still pose a threat to lonely travellers, and the naive.
