Basically, the strongest ones are Sofa's factions
Eagles and Ravens — modern, high numbers, vast territories (Big Birds)
Kestrels use outdated stuff
Owls are the actual high-tech (not just aesthetics) organization
Vultures are PMCs so whatever they can afford
Magpies are insurgents, so also whatever they can afford but way lower budgets

Erazer's Halcyon factions are mostly on par with Eagles and Ravens technology-wise
Karto's Sparrows are somewhere near the Kestrels I think
Heated's Grebes are in range between Magpies and Ravens due to conscripts, volunteers and spec-ops using way different stuff
Jose's Canaries are on Magpie-Kestrel level ig
Tree's Drongos are Kestrel+ tier I'd say

Mine factions are, well...
Ospreys are equal to Eagles and Ravens (another Big Bird)
Cassowaries have some futuristic stuff for their spec-ops, but overall are on par with Ospreys
Silvereyes and Kingfishers technology-wise on Big Birds' level
Cormorants and Lastaukas are somewhat lower in technology than Eagles and Ravens
Sapsans are Kestrel-tier
Storks have some money reserved, so they are in Magpie-BBs range
Albatrosses are lower-end Eagles, while Cardinals are on par with BBs
Chickens are sponsored by Ravens and their allies indirectly
non-made yet Shoebills have some futuristic tech in use but their army is one of the smallest

All of them are small states with only exceptions being Ospreys and Cormorants which are big powers, Storks who are rebels and Chickens being the "humanitarian organization"

as of PMCs...
Outbreakers would have some futuristic tech cuz they are the ones who save the world from weird stuff on daily basis lol
Others get regular stuff they can afford

damm, thanks dude

now for this stupid other question,

L a n g u a g e s,
just put like this

Example:

English:idk eagle?,maybe ospreys,♥♥♥♥♥♥♥ chickens?

russian:Hawks obviously,maybe ravens?

that's comes mostly to personal preferences
I used those mutators a while ago, but iirc
Russian, English (both British and American), French and smth else for Eagles
American English, Chinese and smth else for Ravens
Russian and Arabic for Magpies (but generally speaking they'd use any lang, depends on region)

Hawks are Spanish and Falcons are French (u can just check the vehicles' names)

as of my factions, well
Ospreys would use German and maybe French or any other european lang
Kingfishers, Lastaukas and Sapsans would get Russian (damn, I really need to rewrite their lore so they would not be not!Ukraine, not!Belarus and not!Russia)
for Storks just mix all slavic langs available I think
can't think of others rn

PMC's are just.. multi language, since they are a Private military company right?, so it make sense,

yep
