1	Wooden Barracks	barracks_01	To house levies as they ready for war, they need at least a roof over their head. These simple wooden barracks, thrown together in a hurry by 'willing' carpenters and woodsmen, offer decent protection from the elements... Well, unless it rains.
2	Levying Grounds	barracks_02	By clearing a large swathe of land of any obstructions, we can muster our soldiers in one place for division into units. The clear vision also allows for easier spotting of deserters.
3	Stone Barrack	barracks_03	The sturdier stone barracks offer significantly more protection from the elements, and the carrying of the stones is great training for our men! A 'team-building' exercise, if you will.
4	Mobile Camps	barracks_04	The nature of the barrack is to be mobile, and what better way to stay mobile than to use sturdy and durable leather tents? Those farmers didn't need their livestock anyway!
5	Smithies	barracks_05	By enlisting camp smiths to maintain our levies' rusted spears and bent forks, we significantly increase our chances of success, even though the smiths might have preferred something just a little bit more prestigious.
6	Training Grounds	barracks_06	By putting up training dummies and obstacle courses, we can sift the chaff from the wheat – and that way we know which men to put at the front of the formations...
7	Conscription Centers	barracks_07	By constructing dedicated conscription centers in all nearby villages, we ensure a steady stream of ill-willed, alcoholized troublemakers to swell our ranks.
8	Permanent Barracks	barracks_08	While we often have to move our levies at a moment's notice, the construction of permanent and well-built barracks allow us a place to house the more elite soldiers and officers, should they happen by.

1	Camel Breeders	camel_farms_01	These farms are dedicated to the breeding and raising of camels for use by the military, as well as by local peasants in their daily toil. Camels are flexible and sturdy mounts, ideally suited to a harsh desert climate.
2	Scouting Posts	camel_farms_02	Camel riders regularly travel between the scouting posts, carrying with them supplies and news about current ongoings.
3	Bowmakers	camel_farms_03	Camel cavalry do well when the riders are equipped with bows, and local bowmakers ensure a steady supply of archery equipment.
4	Camel Markets	camel_farms_04	The market is always bustling with activity, with merchants trading hundreds of camels a day. This ensures that our breeders get access to the most resilient and enduring specimen.
5	Nomadic Recruitment Grounds	camel_farms_05	The fierce desert nomads make excellent soldiers, but they don't work for free. By providing them with superior mounts as payment, we ensure their loyalty in future conflicts.
6	Military Stables	camel_farms_06	Large and sturdy stables house our prized war camels, protecting them from both thieves and the harshness of the desert.
7	Armorers	camel_farms_07	Making armor for camels is not an easy task, but the reward is well worth it. A charge by fearsome fully-armored camels can make any horse-based army turn their tail and flee.
8	Advanced Breeders	camel_farms_08	Scientists from all around have gathered here to try and breed the hardiest and intelligent types of camel they possibly can. With proper offices and a large herd of animals, they have created impressive beasts of war!

1	Hide Tents	military_camps_01	Upon calling levies, they are gathered into rudimentary camps where they get to sleep in simple tents. While not the most comfortable, it is a cheap and portable type of camp.
2	Camp Cooks	military_camps_02	By assigning a portion of the levies to collect and prepare food for the rest, more men are lured in from the countryside – drawn in by the smell of food.
3	Training Fields	military_camps_03	Archery targets and dummies give the levies both distraction and a modicum of training, before being thrown into the heat of battle.
4	Watchposts	military_camps_04	Watchposts act as beacons, outlooks, and natural gathering spots. Even when not in times of muster, guards are always stationed here.
5	Camp Smiths	military_camps_05	The camp smiths do simple repairs and keep horses shoed.
6	Mustering Halls	military_camps_06	Dedicated mustering halls placed in every village makes it much easier to press levies into service.
7	Militia Barracks	military_camps_07	Each town now has its own militia barracks, where weapons are stored should they be needed. The barracks also act as a meeting place for the officers responsible for the muster.
8	Levying Squares	military_camps_08	The larger levying squares provide not only a place for soldiers to gather, but also one to train for upcoming battles.

1	Lookout Towers	outposts_01	To track animals (and incoming raids), a series of outlooks are manned by vigilant guardsmen. If a dangerous beast is spotted, it doesn't take long for word to spread so that vulnerable cattle can be hurried to safety.
2	Military Outposts	outposts_02	Along the many roads and winding paths, there are several outposts, manned by guards in the employ of local merchants. Their presence ensures that the area remains peaceful and safe, free of highwaymen.
3	Hidden Weapons Caches	outposts_03	One advantage of living in rough terrain is the ability to camouflage just about anything. Should a raid stumble by, locals can arm themselves with weapons from numerous hidden caches.
4	Palisade Outposts	outposts_04	The rickety old outposts have now been replaced by sturdy and tough palisade towers. What more, they are almost perfectly hidden in the rough terrain.
5	Levying Posts	outposts_05	Near each tower now lies a levying post. In times of muster, levied peasants can safely gather near where they can find both weapon and protection.
6	Frontier Outposts	outposts_06	Contrary to the well-hidden outposts, the frontier variety is meant as a deterrent. Constructed out of tougher materials, the sheer size of these towers is enough to make any raider turn their heels.
7	Scouting Stations	outposts_07	To ensure that our scouts are well-fed and can travel light, we have erected a series of strategically-placed scouting outposts. Well-hidden from the prying eyes of the enemy, these buildings allow unparalleled intelligence to be gathered in times of invasion.
8	Fortified Outposts	outposts_08	Imposing stone-hewn outposts now rise towards the skies, making their presence felt by the soldiers and caravan guards housed within.
