Just a brief suggestion, and I hope I'm not repeating what other people have said (I searched but couldn't find anything), but I think it'd be extremely nice if border patrol could be an ongoing mission, like advanced combat practice. As it is, with the requirement to go back to a base every 15 kills, it's somewhat annoying, and it doesn't seem like it needs to be like that at all. The enemy keeps coming, so why shouldn't the rewards?
Thanks for your time.

usually your supposed to fight bp with more players and the bot you need to kill like 100 bots

but the thing there supposed to come in waves and its not that big of a hassle to go to the station and get the mission again

its fine the way it is

With botting, you earn growing bonuses as you kill more bots. That would be a nice feature in BP as you survive more and more sequential encounters with the enemy. I like diqrtvpe's idea.
