The Kingdom of Teiglin has to maintain a strong military in order to repel the constant stream of chaotic monsters that attack from the borderlands.
There are 2 main groups of soldiers - the baronial militias and the Royal Army.
The baronial militias are recruited from about 1 in 20 of the population and are under the command of each of the barons. The militia are generally not under military command most of the time but have day jobs (farmers, labourers, shop keepers) until called for, either for regular patrolling and guarding or to deal with a particular emergency.
The militia are equipped with spears, daggers and leather armour by their barons, but any militiaman with enough money to spare will upgrade his equipment out of his own purse. Therefore it is not unusual for militia units to contain a wide variety of weapons and armour. Militia are trained to be 1st level fighters (4hp average, 10 in each ability score so no penalties or bonuses)
Alvenir: As there is no immediate external danger to Alvenir, there are only 350 militia, but they are well-trained (50% are 2nd level fighters). A number of would-be militiamen are encouraged to go to Thaldion and join the Royal Army instead.
Bauglir: With its dangerous border and unusually high conscription rates, Bauglir maintains a fighting force of almost 4,000 militia. About a quarter of these are in uniform at any one time, with the rest on standby in the event of a serious conflict.
Brandir: Not the most military of the baronies, Brandir's 700-strong militia is not held in high regard by other barons or the Royal Army.
Glensor: Although there are only about 300 official members of the Glensor Militia, these in themselves are elves with training in sword, bow and spell, more than capable of taking on twice their numbers of orcs and goblins (or humans if need be). Furthermore, the elves of Glensor have a strong warrior tradition combined with a need for self-sufficiency that means that another 1000 elves (both rangers and spellswords) can be mustered in times of war.
Luthien: With a small border with the borderlands and a large population, Luthien maintains an adequate force of 1,300 militia.
Stelmit: The dwarves of Stelmit are a tough breed, and there are always volunteers for the militia. There are 500 proper militia, but probably 1200 other dwarves can pick up hammers and axes in the event of a major conflict. The Stelmit Militia are experienced, as their lord, Blorinor Highhelm, sends companies off to the borderlands of Bauglir to protect the kingdom on a regular basis.
Thaldion: Thaldion maintains a militia of 1100 men, but it really relies on the Royal Army that is based in Thaldion.
Tredgor: As a quiet backwater barony, Tredgor has only 400 militia. However, like Alvenir, a number of would-be militiamen are pointed in the direction of the Royal Army.
(total is 8650 militia)
The royal army is 6200 strong, and is primarily made up from volunteers from across Teiglin. The headquarters is Harmeck Fort in Thaldion barony. Generally speaking the Royal Army is split into regiments 300 strong, and includes an arcane regiment (human magic users and clerics, and elven spellswords), an engineering regiment for both building and destroying fortifications, a reconnaissance regiment (halfling scouts, human thieves and elven rangers) and a logistics regiment (handling supply wagons and pack mules).
There are also 10 infantry, 3 archery and 4 cavalry regiments.
There is no proper navy as such, but the King is entitled to commandeer any ships he might need for the good of the Realm. This is not a satisfactory arrangement, but until the situation with the Chaos-dominated eastern side of Teiglin is resolved there is simply not enough manpower or money for a Royal navy. Three of the Barons have their own ships (the barons of Luthien, Brandir and Tredgor) but these are merchant ships rather than warships, and there is no plan to use them as a coherent force.
The churches of Teiglin are not part of the official armed forces except in the Arcane Regiment, but there are often clerics willing to act as chaplains and medics - perhaps another 200 clerics of lawful and neutral deities are available in times of conflict and these may be assisted by lay members of their churches.
