I'm having some trouble figuring out the best use for the electro-pulse ammo. At first I thought it was to give more options for captures, but it tends to kill the lightly armored wimps like GOs. Is it to help with stunning armored enemies? I've had some luck using it on megapol, for example, but even then it tends to overstun. Is it just to give access to electric damage type?
Also, do secret base missions have a chance to fail if left alone? Or a delay of a few months between the mission and the actual base appearing? I had a moment of horror when I saw a Merc Secret base mission pop up on the ol hyperwave decoder, and basically resigned myself to the fact that base would be there for a loooong time. Got the normal swarm of big ships, and I didn't even bother to land and abort to force the landed ships to start flying again. But so far the base hasn't shown up. The area was Europe and I have it and any conceivable approaches for the supply ships well covered with decoders or blimps, so I don't think I'm missing it. I think it's been 2 months, maybe 3. I'm not complaining, just...confused.
