The direct answer
The official game page describes Warfare as a 50v50 tug-of-war over five sectors. That is the complete confirmed mode shape in the supplied material. It tells you to think about sector control and the direction of the fight, but it does not publish every rule used by the live build.
For a new player, start by locating the sector your squad is addressing and listening for the next objective call. A personal firefight matters only when it helps that broader contest. Keep the explanation simple until the current match interface adds the details you need.
Read the sector contest
A tug-of-war rewards awareness of where pressure is building and whether the squad is attacking, defending or repositioning. The official description does not confirm a ticket pool, capture timer or exact sector transition rule, so those values are intentionally absent here. Use the live objective display for what is happening now.
The five-sector structure is still enough to guide movement. Ask which sector is active, what your squad has been assigned and whether your next action helps control or support. That keeps the mode readable without turning an unverified community explanation into a rulebook.
Use team systems around the objective
The Vietnam setting provides several confirmed tools for a sector fight. US helicopters can deliver fire support and supply drops, NVA tunnels can create surprise approaches, and armed patrol boats let both factions use the river network. These systems can change how a squad reaches or pressures a sector, but their exact availability in a match is not specified by the supplied page.
Other confirmed movement interactions include swimming, climbing, fast crawling and dragging a downed teammate. Treat them as ways to solve a team problem rather than as a checklist of tricks. If a system does not support the sector objective, it may not be the right use of your time.
Warfare and squad roles
The official unit groups include Command, Infantry, Recon, Armour, Mortar and US helicopter units. Public pages in the supplied material disagree on the total number of roles, so this guide does not attach a disputed count to Warfare. What matters for the mode is whether the squad has the kind of support needed for the current sector.
Choose a group after reading the objective, then communicate what you can provide. A squad that needs movement support, observation, pressure or recovery may ask for different help at different moments. No universal role ranking is added because the collected sources do not establish one.
What this page deliberately omits
This Warfare guide does not state ticket numbers, capture rates, exact sector names, map callouts or an unverified vehicle roster. The official page confirms the five-sector tug-of-war, six large-scale maps and six total modes, but not every low-level rule. Leaving those details out keeps the answer anchored to the evidence supplied for this project.
For the broader mode index, open the game-modes page. For the other named structure, open Offensive. If the official game page or a live update publishes more rules, add them as a dated source rather than silently treating a community explanation as permanent.
