Whiteout Survival Brothers in Arms
Brothers in Arms is the Whiteout Survival PvP event where killing or severely injuring qualifying enemy troops earns personal points. The event runs during the regular in-state Sunfire Castle Battle week, but your State decides which attacks its alliances allow. Choose a reward goal and a healing budget before fighting, because City attacks can permanently cost troops. Checked in November 2026.
State Rules Before Targets
State NAP agreements determine which Brothers in Arms attacks your community permits. Read the current alliance announcement before selecting a City or gathering march. Check protected alliances, resource tile rules and any limits on repeated City attacks. These are local agreements, so do not carry a rule from a previous State into a new one without checking.
The event offers individual scoring, but a disputed attack can draw your alliance into the response. Guides recommend asking leadership when a rule leaves room for interpretation. A short clarification before sending a march is cheaper than trying to settle a disagreement after troops have already fought. Keep permission separate from target strength: a weak target is not automatically an allowed target.
Schedule and Duration
The listed schedule is Friday 00:00 UTC to Sunday 00:00 UTC, a 2-day window during the regular in-state Sunfire Castle Battle week. The event runs 1 time per month. Use the event countdown to translate that UTC window into your local schedule, particularly if the opening falls on Thursday evening where you live in the United States.
Plan your available fighting time before the weekend. If you expect to join organized Castle combat, ask officers how that session fits your personal reward goal. If you will be offline, prepare your protection before leaving instead of relying on a reminder at the opening reset. The Fortress and Sunfire Castle guide explains the broader battle context.
Do not confuse this in-state activity with State of Power. The Brothers in Arms scoring window is a reason to review your local rules, while cross-state preparation and battles have their own schedule. Use the full events list to see which activity you are preparing for before committing resources.
Troop Points Table
Qualifying kills and severe injuries to enemy troops award points according to troop level. The table shows the listed values for each tier. A battle report's total casualties and its qualifying casualties are different quantities, so use the event score change to check how a fight advanced your target rather than treating every troop in the report as a scoring result.
| Enemy troop level | Points per qualifying troop |
|---|---|
| 1 | 1 |
| 2 | 1 |
| 3 | 2 |
| 4 | 3 |
| 5 | 4 |
| 6 | 5 |
| 7 | 7 |
| 8 | 9 |
| 9 | 11 |
| 10 | 13 |
| 11 | 15 |
Higher tiers give more points per qualifying casualty. That does not make attacking a stronger army a better decision: the points table describes the reward scale, not the cost of winning the fight. Compare the likely healing and permanent losses with the next reward you want. Review the troop guide when checking the tiers shown in a scout or battle report.

Choose Your Fighting Route
Eligible targets include enemy Cities, gathering troops on resource tiles and Sunfire Castle opponents. Start with the route your State permits and your alliance can coordinate. Guides recommend approved controlled battles for players who want limited milestone rewards without forcing a leaderboard contest. Agree on the conditions before the exchange so both players know when to stop.
Gathering marches deserve a separate rule check. Some States restrict tile attacks even during the scoring event. If your State allows them, evaluate the actual troops before attacking. If you are avoiding combat, guides recommend recalling exposed gatherers rather than leaving them as easy targets while you focus only on the City.
City targets demand the most careful preparation because of permanent attacker losses. An empty-looking map location, a quiet player name or a weak-looking City does not establish what troops are inside. Scout before deciding. For organized battles, follow the assigned attack or defense job and review the formation basics rather than changing your march in a hurry after the first rally appears.
F2P Preparation Tips
Guides recommend choosing a milestone and a maximum healing budget before the event starts. Write down what you can afford in resources and Speedups, then compare the next reward with the cost of the next battle. A smaller completed goal can be more useful to an account than a temporary rank earned by exhausting its army.
Heal existing wounded troops before planned fighting and prepare the resources needed for recovery. Check your protection plan if you will skip the event: review the shield you intend to use and arrange gathering around your offline time. Keep those preparations tied to your schedule, since a shield plan for the morning does little for a City left exposed overnight.
After each meaningful fight, review the report and score before launching again. Guides recommend stopping when losses exceed the value of the remaining reward. Adjusting the plan at that point preserves resources for future alliance battles. Personal points stay a useful goal only while the cost remains within the budget you chose.
Milestone and Ranking Rewards
Brothers in Arms rewards include Gems, Speedups, Resources, Hero Skill materials. Personal milestones reward reaching the listed score targets. The targets can change with State age, so a screenshot from another server is not a substitute for your own reward panel. Choose the milestone whose contents are useful for the next upgrade you already planned.
Ranking rewards have an additional gate: the listed rule covers the top 100 Chiefs with more than 4,000 points. Crossing that score does not guarantee a place, and a place without the score condition is not enough either. Compare the full condition with your expected fighting cost before changing a milestone plan into a rank push.
Brothers in Arms Questions
Is Brothers in Arms the same as the Kill Event?
Players often use Kill Event or KE for Brothers in Arms. Look for the Brothers in Arms event window when checking the actual scoring and rewards. The listed troop scale runs from 1 point at level 1 to 15 points at level 11, so troop level matters alongside the number of casualties.
Does a technically valid target mean I can attack it?
No. Brothers in Arms points and State permission are separate checks. A gathering march or a City can be a scoring target while remaining protected by your local NAP agreement. Ask an R4 or R5 about the current restrictions before attacking; the same target category can have different rules in another State.
Can I use a friendly battle for minimum rewards?
Guides recommend controlled battles with a willing player or a second account when State rules permit them. Agree on the target, troop tier and stopping point first. For example, the scoring table gives 1 point for a qualifying level 1 troop, so low-tier exchanges may require more casualties than their small individual value suggests.
Will an inactive-looking City be an easy target?
An inactive appearance does not show the defending army. Guides recommend scouting for troop tiers, defensive heroes and reinforcements before committing. Brothers in Arms rewards do not remove the risk of permanent attacker deaths. Even a level 11 target worth 15 points per qualifying casualty can be a poor trade if your losses are expensive.
Do all States have the same milestone targets?
Milestone thresholds can change as a State ages. Read the targets in the current Brothers in Arms reward panel and select one before spending healing resources. Do not confuse those milestones with ranking eligibility: the listed leaderboard condition is a place among the top 100 Chiefs and a score above 4,000 points.
