@Tseh these are all similar.
Roaming is more purposeful than wandering, maybe a little more aggressive. Wolves roam, but sheep wander.

in terms of 'about, around, through' etc, they're all broadly the same, it's just a difference in how you picture it.

'About' sounds the most casual, the most directionless, slower and taking your time.

'around' is kind of neutral, it's something you do on an afternoon in a foreign town.

'Through' might be short for 'throughout', if you wander through the town, you're probably going in a definite direction, maybe slowly from north to south.

But if mercenaries roam throughout the town, (eg Spider's gang were roaming throughout town) that means that they're everywhere, all over the place, you really can't avoid them.
