Currently the military of the Republic has a powerful and well trained army, however, there is a need for more specialized units for such situations where the armed forces might be having issues, for this the creation of 2 military organizations was done.

The Ranger Corps are light infantry troops designed for fighting in heavy terrain, long range reconnaissance, and experimental weaponry testing. Rangers excel in raids, ambushes, scouting, quick manouvers, and cross country ranging, in war time they participate and assist the military in their operations. During peacetime they are active in the frontiers and act as border guards by manning observation posts and doing patrols. Rangers are able to go off from the border into the lands of the druids, the starship, and the monks with free reign due to the lack of state presence there in large sections of their lands, on the southern border with Hoshiyomia the rangers mainly travel along the border and don't cross into their territory without official approval. There are a multitude of well hidden supply depots that the rangers use for their guard duties, and due to their guard status and relative freedom of movement, the Rangers also squash any bandits or schizos and investigate any unusual disturbances in their area.
The Rangers are mainly recruited from hunters, axemen, farmers, and postal workers in particular, any potential volunteers to the army that may show enough promise for recruiters are noted and considered for Ranger training. These troops will then go through various training regimes designed to acclimate them to harsh terrain and weather conditions. The Rangers are also trained to some degree in horsemanship to aid their reconnaissance or raiding missions.
On the higher level Rangers are organized into regiments, which are subordinated to the Ranger Corps. Battalions within these regiments operate out of towns that are near supply depots or small military installations in the hinterlands of the Republic, and the companies usually no more than 60 men take over observation posts. The Rangers are of course expected to participate in open battle too when they are not assigned for reconnaissance duty. On the field, they operate in the same role as other light infantries. These light troops are however not expected to directly participate in sieges. Instead they use their maneuverability to harass their foes, attacking baggage trains and feeding intelligence to their superiors. When a Legion mobilizes for war. In the 3rd Schizo Incursion, a battalion of rangers successfully raided a small town 60 miles away from the front, which served as a supply hub of the invaders. The raid successfully destroyed a large number of provisions that delayed the assault on the Fortress near Trenton, which gave the V Legion enough time to mobilize and reinforce the front. The Rangers are also expected to participate in partisan warfare when ordered or cut off from the chain of command. The 8th Battalion is famous for taking out many Schzio Shamans during the Eastern Campaigns. There are 4 ranger regiments active.
I RANGER is headquartered near the capital, serving both as a training reserve and administrative head, this regiment is also used for experimental weaponry testing.
II RANGER is stationed near the eastern frontier.
III RANGER is stationed in the northern frontier.
IV RANGER is a 'nomad regiment' and has relative freedom of movement in the republic, they are tasked with assisting the standard military and the militias around and are available for quick deployments.
The Ranger Corps is directly subordinate to the Commander of the Armed Forces.
Their motto is "Hope for the best, prepare for the worst"

The Trawler Corps are units that are designed for amphibious operations on the coasts of the Republic. They are specialized for quick deployment and light arms, and undergo training alongside the navy for fighting landings, opening beach heads, and the taking of ports. As a result of this training and preparation they are a highly adaptable force and carry great logistical flexibility. One of the reason for their inception is the Islands north of the Penisular. The Navy was concerned about the need to defend and most importantly take back the Fortifications in case of an naval invasion that overwhlemed the Republic. Another part of their existence was in thanks to the Hoshiyomi Navy's assistance, who suggested the creation of an flexible amphibious force aside from the Marines, while the original name of this force was 'Maritime Light Foot Regiment' it eventually changed to The Trawler Corps due to the large amount of recruits being fishermen teams that operated in such boats. They, along with the Navy and their Marines, often participate in exercises with the Hoshiyomian forces. As such they have gained an invalueble amount of experience, which they put to use in various smaller engagements in the past, and would continue to do so in the future. They also serve as extra man that gaurd coastal installations and respond to any anamolies near their station.
There are 2 active Regiments that participate in multiple duties around the Coast. The units are also curiously mixed like a Legion despite their small size. Specialized and retrained engineers from the Engineer Corps would prepare bridges and pulleys to do rapid unloading onto land. There are large amounts of line infantry with smaller teams of light infantry to support them. Artillery is light and oftenly mixed with mortars and howitzers as the navy is generally expected to support them with naval bombardments but they do have access to heavier pieces. For the cavalry they eschew the light hussars, opting for dragoons to support them on the field or act as advanced scouts dur to their ability to fight dismounted when needed. This unique unit is trained to quickly deploy and land using smaller sailing boats and ships, then advance under the support of artillery (naval or otherwise) to their objective. They are assisted by ship board marines or any regular army units as the situation and their commanders dictate.
1st TRAWLER is stationed in the port city of the Republic and have their training grounds further north.
2nd TRAWLER is stationed in the northern port city and are also given tasks of experimental weaponry testing.
These regiments are organized under the Trawler Corps, which are directly subordinated to the Republican Admiralty.
Their motto is "Atlantis won't conquer itself"
