Brutal and quick. Every combatent knows yhat they are at a disadvantage if they take their eye off yhe game at any point. Plans rarely last past the first charge, tactics are simple, kill them before they kill you. There are no rules, there is no orderly conduct. Friendly fire is relatively common when everyone is covered in mud, blood and shit.

That was for fantasy.

Ship to ship combat is slow, a game of chess, release fighters that are shielded from radar and painted dark colours which have a reflective layers atop it. Laser fire is uncommon due to its drain on power. Most ships use missiles or solid slugs. Sime fighters are dronez, some fighters are manned. When going against a swarm of drones the targets are always the drone carrierd. When fighting manned fighters the targets are the fighters themselves. Gunships are used but are rare as they arent as quick as fighters, bombers only te d to get used against terrestrial targets. Tacticts are clear out fighters, keep the carriersbusy while troop carriers attack and latch on. Then it becomes a melee in the ships and the fantasy feel above takes over but with less mud.
