Combat armour is commonplace throughout the galaxy; it is regarded as a standard piece of equipment for mercenaries, soldiers, security officers and most other combat-oriented professions. Because of this, one can see it in virtually every city and space station in the known galaxy.
Though using specific armour for combat is an age-old idea, in recent centuries improvements and minor modifications have been made to the armour. These improvements have allowed modern combat armour to be lighter and more flexible as well as cheaper than their ancient counterparts; it can easily compete against some of the more modern classes of armour in terms of cost as well as quality and durability. These advantages are a few of the reasons that it's a favourite among civilians travelling to harsher systems and among those wanting to evade the law.
