Ruberios Military Strength

Holy Empire Ruberios is noted to be one of the most powerful military powers in the world, with their overall military abilities earning them the attention of the Eastern Empire as one of its primary targets in their path of conquest.

The Holy Church's headquarters, in particular, is noted to be the central most core of Ruberios' military power and the foundation of their nation's morals and justifications, as seen where the church's paladins are charged with eliminating dangerous monsters plaguing their nation and allied nations, as well as fighting off demon lords when they appear.

Technically, the military forces that could be mobilized by Luminous are separated into two branches, namely the Templars (under control of the Western Holy Church) and the Ruberios Standing Military. Sitting on top of both branches are the Ten Great Saints, the pinnacle of their paladins, mages, and heroes that even counts the famous Hinata Sakaguchi as its leader. And even higher up are the Clerics of the Seven Luminaries, tasked with training the next generation of heroes to further strengthen humanity.

Templars
Templar is a catchall term for Church-affiliated fighters sent off to other nations. Said to number in the tens of thousands, they offered the manpower to back up the immense influence the Church had in the area. The most gifted among them form the Crusaders and call themselves paladins. There were about 3,000 templars stationed in the Kingdom of Falmuth, before they were annihilated by Rimuru.

Crusaders
The elite paladins under the Western Holy Church's command, led by Hinata and six captains from the Ten Great Saints. The Vice Captain is Leonard Jester, known as the Childe of Light. Arnaud, Bacchus, Litus, Gerald, and Fritz are squad captains who lead 20 paladins each, making the order a hundred-strong group with each ranked A and above.

Regiment of the Pope's Imperial Guards
These are imperial knights that serve the Pope's ministry, led by Hinata and the Three Sage Warriors. As a regiment favoring individual talents, there are 33 members in total, each with different attire and equipment. All of them possess combat abilities above Rank A, and have enough strength to stand against an entire army. Not only that, several of them united can even stand against a Calamity-Rank threat, making them on par with heroes of this world.

During emergency situations, the Pope’s Imperial Guards can assume direct command of templars stationing in different countries, which is something the Crusaders cannot do.

Underground Forces
Unknown to the human inhabitants, Ruberios also possesses access to the private force of the Demon Lord Luminous Valentine, further bolstering their military power and resources in times of crisis, with several of the Empire's highest ranking officials and confidants being, in fact, Luminous's vampire servants are hiding in plain sight. There are also demi-humans among their ranks.

This force acts as a substantial deterrent against any foreign power that attempts to invade Ruberios due to the presence of Luminous herself and her powerful servants within the nation.

Common Army
Other than the paladins of the Church and the secret non-human forces of Luminous Valentine, Ruberios also has a common army comprised of simple foot soldiers enlisted from the general populace. They are generally given the duty of maintaining internal order within the Empire's cities, villages and towns. During times of war, the paladins of the Holy Church have the authority to assume command of them as their soldiers.
