Within the Caermyr Union, only three of its member states maintain a military as the Urthdysh Federation relies upon the rest of the Union for protection and doesn't expend resources on maintaining a military.
The Arthwyd Empire, Forluc Kingdom and Colryd Confederation each maintain their own military, each with their own unique style. The Colryd Confederation is the most conventional as the Confederation retains the militia system that it inherited from its lowlander origins.
While more organised these days than it originally was back when the Confederation was a group of loosely aligned villages and tribes, the Colryd doesn't maintain a full-time professional military like the Arthwyd Empire or the Forluc Kingdom. Instead, each member-state within the Confederation has its own militia, something that is required as part of being in the Colryd Confederation.
There is no standardisation across the Colryd militias. Each tribe or village determines who is part of its militia and its organisation and while the Arthwyd Empire supplies with bronze weaponry, each militiaman uses whatever equipment they can afford. Size, skill and training also vary across the militias of the Colryd Confederation and ultimately, the militias are looked down upon by their Arthwydish and Forlucan counterparts for their lack of professionalism.
The Arthwyd Empire retains its full-time professional military of sacred warriors. While small in number as a result, the size of the Arthwyd Empire relative to its neighbours has meant that this disadvantage has traditionally not been a factor in any wars that the Arthwyd have fought. As the Catclaws and Cateyes have a history of being competent and loyal, the Arthwyd Empire has never expanded their military beyond them.
The Cateyes operate as scouts and skirmishers. Wearing light armour and armed with a sword plus a sling, bow and arrows, the Cateyes are master scouts as they are able to adjust their bodies to be more agile as needed and are borderline superhuman in both body and mind.
The Cateyes have medium armour and study shields while they are armed arrived with a variety of weapons to suit the occasion. Catclaws have a sword for slashing and stabbing whilst they have a mace for when they need to use a blunt weapon while they have a set of javelins for ranged attacks or in an emergency, a short spear. This combination of weapons served the Catclaws well as it allowed them to fight in a variety of situations while the magic of the Arthwyd lets the Catclaws compensate for weakness in their gear.
Both the Catclaws and Cateyes make extensive use of magic, both active spells and passive blessings. The Blessing of Arthryn gives above average toughness, strength and endurance which allows them to both carry more equipment for greater times without getting fatigued, but also improves their ability to cast magic. Limited ability to shapeshift their physical form lets the sacred warriors of the Arthwyd Empire adjust their bodies to their current task and the ability to see in the dark lets them operate at night with the same effectiveness as they would in the day.
The Cateyes and Catclaws also greatly benefit from the mental effect of the Blessings of Arthwyd and Ymarn as they let the warriors both learn quicker and helps them retain their knowledge, resulting in the Arthwyd military training to a higher degree of skill. Mental improvements also include being more resist to trauma and fear, letting the Catclaws and Cateyes shrug off psychological attacks with greater ease. The Divine Blessings also give enhanced healing to the Arthwydish warriors which allow to recover quicker from wounds suffered in battle to the point that some minor injuries can fully heal in the same battle that they were taken if the battle is a longer one.
The Blessing of Arthryn also grants the Catclaws and Cateyes an unmatched advantage in battle. The blessing gives them a strong resistance to magic that applies itself relatively to all hostile magic that the blessed is affected by. While it leaves them still vulnerable to weaker spells, it protects the Catclaws and Cateyes against stronger spells to the point that spells which would be lethal against a regular person would only mildly harm someone with the Blessing of Arthryn.
The Blessing of Arthryn also gives the Catclaws and Cateyes greater ability to cast magic as their improved stamina allows them to cast more magic before tiring themselves. This is an advantage that the Cateyes and Catclaws leverage to their favour significantly. Tougher defence, increased healing, more accurate attacks, improved weapon skill and improvised ammunition are all things that the Arthwydish warriors use on the battlefield to gain victory.
The Arthwyd military organisational structure is a legacy of its old nature as a group of hunting packs working together. With a defined hierarchy of ranks that forms a chain of command, the Arthwyd military is structured around small tight-knit units that are put together under a clear commander to form a bigger unit that gets progressively larger as you go further up the chain of command.
When it comes to formations, the Arthwyd military uses mobility and flexibility and uses loose formations where each unit is formed into non-tight ranks that have some room to bend under enemy attack. The Catclaws focus on hitting the enemy with their attacks whilst avoiding being hit by the enemy attacks in turn, using greater agility and mobility, coordinated teamwork, superior skill and their magical prowess to achieve this.
Cateyes never engage the enemy and will continuously pelt the enemy at range throughout the battle, using arrows at first than using their slings once their quivers have run out. Agility and fast, the Cateyes use their greater endurance and skill at manoeuvring across terrain to flank around the enemy to either hit them in the rear or force them to split their attention between themselves and the main battle line.
The Arthwyd also make use of boar cavalry as there are many Boarfolk tribes who have settled themselves within the lands of the Arthwyd Empire and will ride into battle in the name of their Cadlon. Relatively small in number and considered separate to the actual Arthwyd military, the Arthwyd Empire makes extensive usage of Boarfolk auxiliaries to provide its armies with cavalry support.
The Forluc Kingdom is somewhere between the Arthwyd Empire and the Colryd Confederation when it comes to its military forces as it uses a both full-time professionals and part-time militias. This is because while the Kingdom itself focuses on its professional military, any Forluc settlement of significant size is expected to maintain a militia to defend itself in the event of the main Forlucan army being unable to respond in time. Maintaining these militia is not the responsibility of the royal court but is the duty of the nobles who rule over the settlements. If a settlement is unable to maintain a militia that meets certain standards, it is grounds for the responsible noble to be stripped of their rank.
When it comes to their professional forces, the Forluc Kingdom uses both regular warriors and sacred warriors. The sacred warriors were originally known as the Chosen Warriors of Nalnir, but as the Forlucan pantheon has formed and Eradan has become their War God, the Forlucan sacred warriors are known as the Bearclaws.
Just as the Arthwyd military values flexibility and mobility, the Forluc military values discipline and order. The Bearclaws operate in tight formations of spear-armed heavy infantry. Wearing heavy armour whilst wielding large shields and long spears, the Bearclaws dominate any infantry battle as unyielding formation with only Catclaws or Boarfolk drive boar cavalry being able to take them on. The Bearclaws aren't limited to just melee either as each one can wield the divine magic of their pantheon, letting each Bearclaw use ranged magical attacks.
The Bearclaws make up the elite core of the Forlucan royal army, but they are supported by light spearmen and skirmishers. Men with spears, shields and light armour make up much of the Forluc military as a numerous and mobile force. Operating in tight and disciplined formation like the Bearclaws, these light spearmen will make up the majority of the Forluc battle line, either defeating their foes or pinning them down for the Bearclaws to move in and break them.
The skirmishers of the Forlucan royal army are its latest addition and they are based off of the Arthwydish Cateyes. Lightly equipped and primarily wielding ranged weapons, the Forluc skirmishers act as scouts and skirmishers for the Forlucan military. While not as good as their northern counterparts, theses skirmishers are still dedicated scouts and capable of doing their job. In battle, they act as skirmishers, harassing the enemy forces at range before the Bearclaws and light spearmen move in.
The federal government of the Caermyr Union and the Council of Arthryn also maintain their own forces, but they are limited in number and are styled after the Arthwydish Catclaws and Cateyes. In times of war, these Arthrynite sacred warriors are considered to be part of the Arthwydish military forces and operate as part of the Arthwyd armies, including being incorporated into their command structure.
