Military campaigns are unlocked by building the [barracks](\minedefense\wiki\Industry#barracks), which is unlocked after reaching a total population of 50 through the [habitation](\minedefense\wiki\Industry#habitation) construct.
## Launching a Campaign
You can launch a campaign as soon as the [barracks](\minedefense\wiki\Industry#barracks) is built. The enemy's initial strength is dependent on how many goblins and spiders you've killed, and increases after each successful campaign. The soldiers you have available is equal to half of your population. You can increase the strength of your soldiers by paying steel and food to train them from the military page and through the [blacksmith](\minedefense\wiki\Industry#blacksmith) industry construct. The outcome of each battle is determined by random values chosen based on the enemy strength and the army strength. The values chosen are based on a Gaussian curve centered on each respective strength with standard deviations of 1/5 of the strengths. If your army's random value is greater than the enemy's, your campaign will be successful.
## Spoils of War
After each successful military campaign, you will be rewarded a random amount of [iron](\minedefense\wiki\Resources#iron), [coal](\minedefense\wiki\Resources#coal), and [steel](\minedefense\wiki\Resources#steel) based on the enemy's strength; the higher the enemy's random roll, the higher the average resulting rewards. In addition, you will have a chance to receive an adamantium reward based on the number of military victories you have won. Between 0-50K victories, you will receive (# campaigns won / 1001)5 adamantium each time you find adamantium on the battlefield. After 50K victories, you will receive an additional ((# campaigns won - 50K) / 253)4 adamantium. The initial chance to find adamantium is 7%; the chance increases to 21% with the purchase of the [War Vultures](\minedefense\wiki\Upgrades#warvultures) upgrade. With enough military victories, the adamantium reward from battles can greatly diminish the wait to get 100 [dragon hunters](\minedefense\wiki\Hirelings#dragonhunter) for [Human Fusion](\minedefense\wiki\Upgrades#humanfusion). During each successful campaign, between 5-10% of your army will perish. During unsuccessful campaigns, between 25-50% of your army will be lost. After each victory, goblin and spider levels increase by an amount directly proportional to the difference between your army's random roll and the enemy's; the higher the difference, the greater the increase in enemy strength after the battle.

## Graveyard
The [graveyard](\minedefense\wiki\Industry#graveyard) provides a percentage boost to your army strength based on the total number of soldiers you have lost in battle. The boost is equal to log(# soldiers lost)1.9 percent of your army's strength. After purchasing the [Blind Revenge](\minedefense\wiki\Upgrades#blindrevenge) upgrade, you have the option to turn on automated battling through the graveyard construct window. However, as the enemy's level will quickly catch up to your own, you will begin to lose around half of the automated battles, assuming your population regenerates completely between each battle. With the [Strike Blindly](\minedefense\wiki\Upgrades#strikeblindly) upgrade, each Blind Revenge attack is accompanied by an automated bombing of the enemies from the [blacksmith](\minedefense\wiki\Industry#blacksmith) if you can afford it. This keeps the enemy's level low and will eventually stabilize at a level where your army will defeat the enemy's army every time. The enemy's level will likely stabilize at a high enough point where it is difficult to destroy attacking goblins and spiders on the main screen, so be sure to maintain a large enough mage army to fend off the invaders if you want the valuable drops from [rebel goblins](\minedefense\wiki\Hirelings#Rebellious goblins ).
