This Star Trek Fleet Command FAQ answers the questions new and returning commanders ask most: what chat shorthand like RoE, OPC, OPL and KOS means, how Transwarp Cells work, where to find armadas, how to get officer badges, and where each part of the game is covered on this wiki. Every answer is short, and each one links to the full guide when there is more to say.
Star Trek Fleet Command terms and abbreviations
Alliance chat moves fast and leans on shorthand. These are the terms you will see most often, with what they mean in practice.
| Term | Stands for | What it means in the game |
|---|---|---|
| RoE | Rules of Engagement | Player-made rules a server agrees to follow, such as not attacking miners. They are not game rules. |
| OPC | Over protected capacity | A ship carrying more cargo than its protected hold can keep safe. The extra can be stolen. |
| OPL | Over protected limit | Same idea as OPC: the cargo above your protected amount is at risk. |
| KOS | Kill on sight | A player or alliance that others will attack wherever they find them. |
| Ops | Operations level | Your Operations building level, which sets what you can build and where you can fly. |
| PvP / PvE | Player vs player / player vs environment | Fighting other commanders versus fighting hostiles, armadas and missions. |
Frequently asked questions
What is RoE in Star Trek Fleet Command?
RoE stands for Rules of Engagement. It is a set of rules the players on a server agree to follow, not something the game enforces. Common RoE rules cover when miners can be attacked or which systems are off limits. Each server writes its own, and some alliances require members to follow them. Breaking RoE does not break any game rule, but it can make you a target for the alliances that agreed to it.
What does OPC or OPL mean?
OPC stands for over protected capacity and OPL for over protected limit, and both describe the same risk. Every ship has two cargo numbers: its total cargo capacity and its protected cargo. Protected cargo stays with you even if the ship is attacked and destroyed. Anything above the protected amount can be taken by the player who beats you. When someone in chat warns you that you are OPC, they mean part of your haul can be stolen, so either head home or accept the risk.
What does KOS mean?
KOS is short for kill on sight. A player or alliance marked KOS will be attacked wherever they are found, usually because they broke the server’s RoE or are at war with the alliance that declared it.
How do Transwarp Cells work?
The standard Transwarp Cell is used to travel to special Borg systems. You earn them from daily chests once you have built the Vi’dar, and you can hold a maximum of 8. A cell is spent when you warp to one of those Borg systems. Other cells work the same way for their own regions: Rogue Transwarp Cells open locked Rogue systems with 3★ ore, gas and crystal, and the G4 and G5 Dominion Transwarp Cells open Dominion systems with 4★ and 5★ materials.
How many Transwarp Cells can I hold?
The daily-chest Transwarp Cell caps at 8. Spend a few before you claim more, or the extra has nowhere to go.
Where do I find armadas?
Armadas spawn in fixed systems by type, level and rarity. The armada locations finder lists every armada system with its level and the warp you need to reach it, including the solo armadas you can run with your own ships.
How do I get Command, Science and Engineering badges?
Officer badges are used to promote officers. The game says they are earned by defeating roaming ships and taking part in events, and Minor Commendations can be exchanged for them in the Federation, Klingon and Romulan faction stores. The officer badges guide covers every source and which officers to spend them on first.
What is the Syndicate?
The Syndicate is your personal progression track. You earn Syndicate XP from the daily Syndicate chest and store packs, and each of its 65 levels adds permanent account-wide buffs, officer shards or presets that stay with you in any alliance. Its alliance counterpart is the Emerald Chain, which your alliance levels up through Alliance Tournaments. The Syndicate and Emerald Chain guide lists every level of both.
What are ship refits?
Refits are permanent upgrades for a single ship, unlocked with that refit’s shards. Some are cosmetic skins, some add combat or mining buffs, and some unlock an active ability such as cloaking or Field Repair. The ship refit list has every refit with its shard cost.
How to use this Star Trek Fleet Command wiki
This wiki covers the game system by system. If you are looking for something specific, these are the fastest starting points.
- Ships: the ship guide lists every ship by grade and class, with build costs, abilities and tier stats on each ship page.
- Officers: the officer index links every officer page, and the officer tier list ranks them by use.
- Star systems: the systems list and the interactive Star Trek Fleet Command map.
- Hostiles: the hostile guide covers where each hostile spawns and what it drops.
Pages are updated as the game changes. If a number on a page looks different from what you see in game, remember that research, buildings and officers change most values, and the pages list base values unless they say otherwise.
About Star Trek Fleet Command
Star Trek Fleet Command is a free-to-play strategy game published by Scopely for mobile and PC. You run a starbase, build and upgrade a fleet, recruit officers from across Star Trek, and work with an alliance on a shared server. Progress comes from mining, fighting hostiles and armadas, running missions and events, and climbing the research trees. Most of the shorthand above comes from the player-versus-player side of the game, where cargo, territory and alliance politics all matter.
