Yeah, that feels about right. Sanctus Petrus balances its pre-medieval technology with divine strength, with the respective deities intervening on their believers' behalf as much as permitted by the Edicts of Guthix. Nordenstadt's mostly medieval technology is balanced by powerful magic (e.g. weather control
). Salamandastron's technology is about 1700s-early 1800s; they have a vicegrip on most of the Western Sea, balanced by their fish-out-of-water situation farther from the coast. Utopia's technology is ultra-modern, think 2142 or so, but they have no real naval presence, their hypertech navy eradicated by a massed Nordenstadt assault on their shipyards in the second year of the war - not to mention they are the least economically developed nation among the four right now.
Sanctus Petrus is a monastic civilization, so they have not much in the way of combat technology. Warrior-monks fight with their hands, or occasionally with staves or maces. That doesn't mean they're pushovers, though - after all, who needs technology when you have God or gods on your side? 
Nordenstadt's war tech was elaborated on a little in my last post; that should give you an idea of what they have.
Salamandastron has swords, awesome ships, black-powder firearms, cannons, and now repeating rifles.
The Bloodmoon Order has a motley collection of stuff salvaged from the ruins - industrial machinery that survived the warfare, as well as a collection of projectile and rocket weapons ranging from pistols to heavy machine guns to mounted railguns for safehouse defense. The few intact buggies, as well as other vehicles jury-rigged from scraps of wreckage welded together and an electric motor and some guns strapped on, compose its fast-attack force.
