I actually have experimented with this. A military outpost, infact.
Sort of.
It just had two snipers protecting a sort of checkpoint thing and a couple of other bots that sit behind cover and shoot at you.
There is also a sniper event I need to fix. It was in an older version, where botmod was much more prominent.
An admin-activated event would spawn three bots with silenced SMGs around the survivor base, who would then try to pick off players. They didn't move, jump, or crouch.
Just spawn on the outskirts/in the hilly area and shoot.
There was also a similiar one that spawned a bot with a mortar, too.
I'd never arm a bot with a sniper, raycasting or instant-kill weapon for some pretty obvious reasons.
I'll re-download bot mod and fix up those events.
As for the second survivor base, I've tossed up the idea but I'm just not sure how to employ it properly. The thing with NPCs, is they are very very hard to role play with. Four bots with Silenced SMGs laying down suppressive fire on players is fine, you can work with that, but a whole base run by NPCs could get complicated. I want to keep things simple.
Think about how the military is run in the server:
Sometimes, nothing ever actually happens and players just roleplay it.
stuff! A sniper shot me! Get down!
I've seen it happen a few times and it has always gone really well. Gentoo pulls it off pretty well.
Sometimes, there are bots playing the role of the military. This could take form of ambushes or mortars, where the bots are in obvious locations and are easy to take down. But they spawn in numbers and are more accurate than the player, so they still pose a threat and some challenge. That way you don't feel patronized, but can still have fun.
When they spawn is also completely controlled by admins, so they wouldn't pop up in the middle of a role play. They don't follow an automatic rotation.
When there is a vehicle event, say an apache doing a sweep or a jet doing a quick bombing run- even the occasional UAV doing an area scan -it is controlled by admins. I've done that with Ceist and Electrk, and each time it goes very very smooth. Vehicles never shoot to kill. It's always shoot to miss or shoot to injure. I don't want to ruin the roleplay by sparking a deathmatch.
With a whole base controlled by bots... I don't know... It could just be really, really clunky.
I'll certainly have a quick play with it and get back to you, but until then don't expect to see anything too heavily bot-related in the server.
However, I'll fix the sniper and mortar events. I do miss those a little ;P
