Perks are a type of gameplay mechanic associated with the level up system in Battle Brothers. 1 Perk point is gained with each level up. they will be able to acquire powerful perks, independently of their Attributes.
To unlock, for example, the second perk row, you need to spend one perk, to unlock the third row you need to spend two perk points. These two, however, can be used in the first perk row and you will still gain access to the third row.
After you read about what each perk does, you can use the tool "Battle Brothers Perk Calculator", made by EveryCrime. It let's you visually calculate how you can spend your perk points on a character with a certain level or how you have to progress in order to achieve the perk combinations you want.
Adapt to your opponent's moves! Gain an additional stacking + 8% chance to hit with each attack that misses an opponent. Bonus is reset upon landing a hit. Note: For the purposes of a reset on ranged attacks, hitting terrain blocking the target counts as a hit and will reset the counter.
Cripple your enemies! Lowers the threshold to inflict injuries by 33% for both melee and ranged attacks.
Bring it on! Hitpoints are increased by 25%, which also reduces the chance to sustain debilitating injuries when being hit.
Once per battle, upon receiving a killing blow, survive instead with a few hitpoints left. The next hit is likely to kill you for good, of course.

Nailed it! The penalty to hitchance when shooting at a target that has no clear line of fire is reduced from 75% to 50% for ranged weapons.
