As said here, devs want feedbacks about encounters. So I suggest we use this topic for everything we have to say about them.So, my first thought:NCR army, that you encounter below NCR Military Camp, has some problems.They often encounter Remnants of Master's army, which means there are huge explosions, player just has to spectate and to loot.The soldiers are actually named "Weak Gun Guard" and so on.The background of it is a bit of a problem, to me NCR Army encounters look like nerfed patrols. They have low or middle-tier stuff, while patrols (and caravans) have CAs and great guns; so is there some kind of weird hierarchy that means that you are first in NCR Army (with poor gear), then in patrols, where you have great stuff? In my opinion, NCR Army could be made very different from NCR patrols by increasing their number, for example. Like, 20 guys at least. This way, they could keep this poor gear, or if they had better gear they would really look like the part of an army.
If you want to make enemies, try to change something.
NCR Patrol? Or Rangers? Rangers and NCR Army are seperate things.
Masters army aren't stopping loot?
As for where Masters stuff occurs, it comes from the Masters vault - I tried to have a logical spread of things - certain raider groups occur centred on an imagined raiders base for example. These groups are currently identical, but will change over time.
Cents did get a little too close to the Hub though and should (hopefully!) be further away after an update.
I see an NCR Rangers group, but no patrol. If there is a Patrol they'll should disappear, like Caravan encounters will eventually.
I have no problem increasing the Army encounter size, Gear can vary, Hunting rifle will largely be the standard issue.
Perhaps you think of the Hub Patrol?
