Such men have little to do with standard military protocols and practice, or even organisation, often taking up arms in extraordinary circumstances. This lack of discipline means that they can sometimes be extremely brutal, even brutish, in their behaviour. This can work in their favour, in that it gives enemies pause for thought. More typically, their lack of discipline counts against them, and faced with a well-ordered force they can be at a disadvantage. In such a case, their mobility can be a boon, allowing them to harass an enemy and withdraw as soon as the fight goes against them.
