Helios has a total of approximately six thousand soldiers across the chain of garrisons watching over all enemy movements from the Aegean coasts, warlords of Bulgaria and the Ottoman Sultanate.
Not all of the six thousand men can be used to storm the enemy lines though, of the six thousand men there are four hundred men who are required to guard over the coast and the watch points across the borders so that Helios would not be completely ignorant if the enemies try to sneak into his back, and there are a thousand men who are responsible for the logistics, maintenance, transport, intel, rations and other aspects that are necessary for this army, leaving it to only around four thousand men that Helios can deploy for now, this size is of course never comparable with the sheer force of the King of the Franks or the corona regni of Polonia (Poland), but at least it is still a formidable force against the Ottomans in the region.
