Whats in a bunker?

[Marcello]

"What i was asking was i was thinking of putting new weapons in the bunkers weapon slot but i wanted to know if there was some data in what was actully in them so i can mobhack more bunkers with the right weapons."

In the modern era, give or take a few exceptions such as some cold war fortifications built in Switzerland, Italy etc.bunkers are not armed with "fixed" weapons.
Rather they usually are field fortifications (although sometimes permanent in nature such as all those albanian
pillboxes built during Hoxha rule). As such they generally will be armed with whatever infantry weapons available to troops who occupy them. Typically machine guns, rifles and stuff like that. Usully no antitank weapons as firing most ATGMs and RPGs from small enclosed spaces would be unhealthy.
Artillery (both normal and antitank) is usually entrenched rather than put inside bunkers, for the sake of range or mobility (if you put an ordinary artillery piece in a bunker you have to demolish it or leave very large openings to bring it out if you have to move).
These are some general points. There are exceptions and many more things to be said but I lack the time at the moment to go more in depth. Hopefully I will be able to later.
