The difference between Hrossey and Hjaltland could not be more stark. Where Hjaltland is a densely vegetated and mountainous jungle world, where as Hrossey is composed of vast open plains. This in turn is reflected in the planets military, with the Hrossey yeomanry being a highly mechanised force, with significant numbers of chimeras. This is to enable the rapid deployment and movement of troops around the surface of the planet. Due to the low importance and low population levels on the planet, Hrossey does not have to supply troops for service in the Astra Militarium, and has rarely done so, arguing that it is a better use of such man power for the production of food supplies than soldiers. The only time that the planet has provided troops for the AM at the beginning of the Sabbat Worlds Campaign, when 5 regiments, the 1287th to the 1291st, were mobilised. At the time, this amounted to over half the regiments that were kept as permanent PDF units on the planet. However, with the current situation within the Sabbat Worlds, a "request" was made to the governor of Hrossey for the mobilisation of a regiment of the Yeomanry, which lead to the 1313th being mobilised alongside the 851st Hjaltland L.I.
With the separatist rebellion on Hjaltland, the 1313th Yeomanry was deployed alongside the 851st L.I. on to Hjaltland. This meant that the yeomanry had to abandon there chimeras and take to the forest on foot, leading to significant numbers of casualties, up to 90% in some squadons. As a result the 1313th is only a shadow of its former self.
The 3rd squadron was one of the luckier squadrons, being posted to support the 1st company of the 851st Hjaltland L.I. and as such, have survived in greater numbers. This is also due to the actions of the commanding officer, Colonel Leith, a man of outstanding courage and determination. The colonel is not afraid to lead from the front, sharing in the risks of the soldiers under his command. While this means taking great risks, it also enables the colonel to react to any situation at a moments notice, making sure the best units are in the best position.
The 3rd squadron is full equipped to deal with any situation, with the 4 sections each armed to deal with a specific task, from tank hunting to taking the many monsters that walk to field of battle. While the 851st rely on numbers to overwhelm the enemy, the 1313th rely on the speed of their chimeras and the imperial navies aircraft to make up for the lack of numbers.
The Yeomanry regiments of Hrossey are supported by various artillery regiments, notably the 56th Artillery Squadron, which is armed with Wyvern heavy mortars, although a few venerable griffins are stored by the squadron. Currently the 3rd wynern batteries 2 remaining wyverns are on attachment to support the 851st.
In addition to the regular forces on Hrossey, there is the local Militia, formed to many of the sons of the ruling land owners. The main unit of the militia forces are the Lancer units, often named after the land owner funding the unit, such as the Kirkpatrick Lancers. The mount of choice for many units is the plains cat, a large tiger like animal capable of carrying a man with ease. The majority of the time, these units are used to hunt down other wild plains cats that are bothering the herds or even just for fun, but in times of war, they are deployed as rapid reaction forces to hunt down any small bands of enemy soldiers that maybe in the area.
In addition to the forces of Hrossey, the planet is also home tons small number of units from Helliar. These tank units are part of a mutual agreement between the two planets, which also involves the stationing of some Hrossey Yeomanry units on Hellier. This arrangement is seen as mutually beneficial as it means each planet can be more specialised in its recruitment and training. At present the Hellier 12th tank squadron is attached to the 1313th yeomanry, with the 6th tank troop supporting the 3rd yeomanry squadron. The 6th tank is commanded by Major Antoun Turvous, astride his Leman Russ Punisher, who is always flanked by his to troop mates in there Leman Russ Battle Tanks.
