Start With Troops, Not Counterattacks

Defense matters because an attack immediately removes the attacker’s committed troops from their total troop count. That can reduce their troop gain rate and create an opening for another player to attack them. In OpenFront, a stable defender can benefit when an opponent overcommits.

The central answer to defending is simple: preserve enough troops to remain a credible defender, then make counterattacks only when they improve your position. All troops that are part of your maximum troop count act as defenders. This means your available troop total is not just a resource for expansion; it is also your frontline protection.

Ground combat happens when an enemy attacks territory bordering their own territory. An attack is directed at all territory with the same owner that borders the attacker. Because combat can affect a connected section of your border, defense is about the relationship between troop totals, terrain, buildings, and the size of the border being contested.

| Defensive principle | What the combat rules say | Practical meaning | |---|---|---| | Keep troops available | Troops in your maximum troop count act as defenders | Avoid leaving your territory weak while attacking elsewhere | | Watch enemy commitment | Attackers immediately lose committed troops from their total count | An overcommitted enemy may have reduced troop gain and weaker defense | | Counterattack selectively | Moving troops to counterattack reduces your troops by the same amount as the attacker’s | A counterattack is a tradeoff, not automatic protection | | Protect border conditions | Border size affects attack speed and efficiency | Pay attention to where your territory meets the enemy’s |

Do not treat “having territory” and “having defense” as identical. Tile ownership influences maximum population, while the troops within that maximum count defend you. More tiles can therefore support greater capacity, but an expanding player still needs to decide how much of their troop strength remains available.

A player who sends every troop into an attack can significantly reduce their troop gain rate. The combat guide specifically warns that sending 100% of troops is ill advised in almost all situations, partly because a third party can take land while that player is attacking the first defender. The same risk applies to you: when you defend one threat by committing everything against it, you may expose yourself to another.

Read the Factors That Shape a Defense

OpenFront combat is not decided by troop totals alone. Attack speed and attack efficiency depend on several listed factors, including terrain, Defense Posts, troop ratios, border size, player status, and the attacker’s and defender’s type.

This is useful for defense because it changes what “safe” looks like. A border that is hard to attack may need less urgent intervention than a favorable border for the attacker. Conversely, a defender with a large troop total should not assume that total settles the outcome if the terrain or a Defense Post changes the losses involved.

| Factor | Source-described effect on combat | Defensive takeaway | |---|---|---| | Terrain | Affects attack speed and efficiency | Consider terrain before deciding whether to hold or counterattack | | Defense Posts | Their presence affects combat; a defended tile in range has a loss multiplier | Defense Posts can materially change a threatened tile’s resistance | | Troop ratio | Attacking and defending troop ratio affects losses | Keep enough defenders that the ratio does not become favorable to the attacker | | Border size | Implicitly affects attack speed and efficiency | Border geometry is part of the defensive situation | | Fallout | Affects combat calculations | Fallout status can alter the cost of attacking a tile | | Connection, AFK, Traitor status | Listed as combat factors for players | Stay connected and avoid status disadvantages when possible |

The source’s calculation shows that plains, highlands, and mountains have different terrain defense values. This is a concrete reminder that terrain is not cosmetic. A defender should identify which threatened tiles are on each terrain type before judging an attack only from the map’s overall appearance.

| Attacked tile terrain | Terrain defense value in attacker troop-loss calculation | |---|---:| | Plains | 0.8 | | Mountains | 1.2 | | Highlands | 5 |

The highlands value is especially notable in the published calculation. It is higher than the values shown for plains and mountains, so an attacker’s troop loss calculation changes substantially by terrain. A player learning defense should avoid assuming every border costs an attacker the same amount.

Defense Posts also have a direct listed value in the attacker troop-loss calculation. When a Defense Post is in range of an attacked tile, the shown multiplier is 5; without one, it is 1. The source does not provide a placement guide here, so it would be unsafe to claim an exact building pattern. What it does support is the basic defensive conclusion: a threatened tile’s proximity to a Defense Post is important information.

Manage the Troop Ratio and Counterattack Choice

The troop ratio is one of the clearest parts of the combat calculation. The source defines the ratio as defending troops divided by attacking troops, then clamps it between 0.6 and 2 for the attacker troop-loss calculation.

That structure gives defenders a useful way to think. If defenders are greatly outnumbered, the calculation does not keep falling below the lower limit. If defenders have far more troops than attackers, the relevant ratio is capped at the upper limit. This does not mean combat has only one deciding factor, but it confirms that troop balance is central.

| Defender troops ÷ attacker troops | Clamped ratio used in the calculation | |---|---:| | 0.6 or lower | 0.6 | | More than 0.6 and less than 2 | The actual ratio | | 2 or higher | 2 |

When defending, you may send troops from defense into a counterattack. The source says this creates an equal decrease in your troops and the attacker’s. Sometimes that is wanted, and sometimes it is not. The right decision depends on whether the reduction improves your overall safety rather than merely responding emotionally to an invasion.

Before counterattacking, check these questions:

  • Will moving troops out of defense leave another border exposed?
  • Has the attacker already committed enough troops that their own defense or troop gain rate is weakened?
  • Is the contested terrain favorable for making the attacker pay more?
  • Is a Defense Post in range of the tile under attack?
  • Are you responding to one attacker while a third party could exploit your reduced troop count?

A counterattack is most defensible when it changes the opponent’s ability to continue attacking without creating a worse vulnerability for you. The source does not give a universal troop percentage to commit, so do not invent one. Instead, use the visible troop balance and the listed combat factors to decide whether a counterattack is worth the equal reduction in both sides’ troops.

Attack speed and efficiency are also influenced by the number of tiles owned by both sides. The listed calculation includes effects for large attackers and large defenders. That means a player should reassess defense as map size changes; an early fight and a fight involving much larger territories may not behave identically.

Build a Defensive Decision Routine

A good defensive routine reduces rushed decisions. When an enemy begins an attack, first establish what is happening at the border, then decide whether holding, counterattacking, or conserving troops best protects your territory.

Start by locating every tile involved. Ground attacks apply to territory with the same owner that shares borders with the attacker. A wide or complicated contact area can therefore be more consequential than one isolated tile.

Next, inspect the defensive conditions. Look for the terrain type, whether a Defense Post is in range, whether fallout is present, and the current troop relationship. These are all listed combat factors, so they are stronger evidence than a guess based only on who appears larger.

| Check | Why it belongs in a defense routine | |---|---| | Current troop count | Your troops in the maximum count are your defenders | | Enemy troops committed | Attacking troops were immediately removed from the enemy’s total count | | Terrain | Terrain changes the attacker troop-loss calculation | | Defense Post range | A nearby Defense Post changes the published loss multiplier | | Border size | It affects attack speed and efficiency | | Other nearby opponents | A third party can exploit a player weakened by an ongoing attack | | Connection and status | Connection, AFK status, and Traitor debuffs are listed combat factors |

Then choose restraint when the facts do not justify a counterattack. Keeping troops as defenders may be stronger than reducing both sides’ totals. This is particularly relevant if the enemy has already committed heavily, because their troop gain rate may have changed and another attacker may pressure them.

If you do counterattack, treat it as a deliberate reallocation of defense. You are not creating troops; you are moving troops from your defensive total into an attack, with an equal decrease relative to the attacker. Recheck your remaining borders immediately afterward.

Finally, remember that conquering all of an enemy’s tiles grants their gold. That reward can make finishing a conflict attractive, but it should not erase the defensive risks described above. A player who pursues the final tiles with all available troops can still become vulnerable to another opponent.

FAQ

What is the basic answer to openfront how to defend?

Keep sufficient troops in your maximum troop count, because those troops act as defenders. Avoid automatically sending all troops into an attack or counterattack, since doing so can reduce troop gain and expose your land to another attacker.

Should I send 100% of my troops to stop an attacker?

Usually no. The combat guide says sending 100% into an attack is ill advised in almost all situations. It significantly decreases troop gain rate and can let a third party take territory while you are fighting.

Do Defense Posts help with defense?

Yes. Defense Posts are a listed combat factor. In the published attacker troop-loss calculation, a Defense Post in range of the attacked tile uses a multiplier of 5, compared with 1 when no Defense Post is in range.

Does terrain matter when defending?

Yes. Terrain affects attack speed and attack efficiency. The published terrain defense values differ among plains, mountains, and highlands, so a defender should evaluate the actual terrain at the threatened border.

Is counterattacking always the best defense?

No. Counterattacking moves troops out of defense and causes an equal decrease in your troops and the attacker’s. It can be useful, but only when it improves your broader position without exposing another border.
