Base defenses

[dbt1949_slith]

Do these do any good in small numbers, say 2-3 plasma or something, or do you need really large numbers for them to be effective?
Them battlecruisers are still getting thru pretty easily with my three defense stations. I went and sold them off and will rely on my tanks and men for the main base.
Do the UFOs attack you fighter bases?

[Hanal]

Yes, they can attack your fighter bases. Once this happens, you have 10 days to send your troops in and eliminate them or the base becomes a fully functional alien compound.

[GalacticOrigins]

Any base without defenses will get attacked and conquered again and again. Don't build mega-defenses once you liberate a base, that just draws flies (BIG ones). Try and have a few defenses to stop the basic ships from coming in, but keep base costs low. BC and up are too powerful to stop, even with a fully defended base built up with good defenses.

[Traveler]

The easiest fight has to be the main base defence.  The aliens wont blow open the walls, so I just put troops in front of the doors and wait.

  Base defense is not worth it unless you use one of the mods and even then you will need 3-4 current generation defense just to stop and dmaged BC or above. SO I would say forget about it and just look at it as an opportunity to get morexp for your troops.
