Project Atlas is a modded Minecraft server on 1.20.1 that uses a Europe map and goes heavy on geopolitics and war.
You can pick a nation and do stuff like fly fighter jets fight on the frontlines or lead a tank division. You can also try to be the president emperor or dictator if you want.
It is free to play and there is no application. You can start your own defense company or trade company or even make your own nation. The server is new and it plans to release when it hits 25 members.
Posalon is a worldbuilding server that just reopened after a 3 week dev break. It has been running for over 3 months and it has an active community.
The main idea is making nations and building a big lore story together. You can start your own nation and try to make history or you can join another group and help them grow.
The big plugin here is Movecraft so people can build ships tanks and planes out of blocks. There is also Brewery X plus lands and a market and an auction house and even a stock market. It also has guns and seazones and more.
It supports both Java and Bedrock. It is not focused only on military since the goal is worldbuilding and community lore.
I found a modded Minecraft server that is doing a zombie apocalypse modpack on Forge. It is built for people who want to actually stick around and play not just quit after the first day.
The pack has guns and military vehicles plus zombies. It also has tech stuff and a Lost Cities style world so it feels like ruins and survival. It is a medium to big pack with 373 mods so you need a decent computer with at least 16 GB of RAM.
They are doing a fresh start and the server begins on Saturday around 1 to 2pm EST. They are mostly looking for active players who will keep playing week to week.
This is a modded Minecraft event that runs until April 12th. It is built around resource management logistics and strategy more than just shooting.
Players are pushed to build big infrastructure like dedicated mines factories oil refineries airfields armories garages and artillery posts. The server does not force fighting so groups decide their own politics and deals. There is a strong incentive to roleplay and let the story grow from what players do.
By the end of the event a winning team can earn a lead role in the next project. Player made lore is meant to carry forward into a bigger story. The host stays neutral and runs a news group that reports on the war as it develops.
Era SMP is a geopolitical Minecraft server but it has a big tech and progress vibe too. It uses a bunch of plugins so players can work on technology style projects without staff needing to do a lot.
I saw stuff like electricity and machinery plus moveable vehicles. There are also higher enchantment caps and a taller world height so building and gearing up feels more extra.
It feels like the kind of server where you always have something to work on. You can plan projects mess with tech and watch the world on a live map.
Iron OverWorld is a brand new whitelisted Forge server on 1.20.1 and it is all about industry nations and modern war on a custom Earth map.
People form countries and claim real world land then fight over resources. Some players will build huge factories and others will run trade empires or plan invasions.
It uses Create with heavy addons so you can automate a lot and build big train networks. Combat is not vanilla because it uses firearm mods plus big cannons for sieges and artillery.
There are also air and ground vehicles for battles and moving supplies. Proximity voice chat is enabled so diplomacy and squad comms are a big part of the vibe.
It has some quality of life mods like simple storage backpacks map tools and corpse runs. Since it is whitelisted they are trying to keep the community higher quality.
This is a modded server that is all about war with guns and crazy machines. When I joined I saw people using guns planes helicopters and tanks and it looked like a huge battle.
The main goal here is to make war fights fun but not totally miserable. Griefing is not always allowed. It is mostly allowed during wars so the whole world does not get wrecked for no reason.
Over one thousand people have joined this server already so it feels like one of the biggest modded gun servers I have seen. There are lots of players who like modern gameplay with modern guns and vehicles and it feels really active.
If you want a server where you can fight big wars with powerful weapons and still have some control over griefing this server is made for that.
