2.6 Dealing with alien infiltration of governments
Aliens will attempt to force governments to abandone the X-COM
project by attacking that country mercilessly until the
government signs a treaty with them. We tried this on Hitler
just before World War II. It did not work then, it will not work
now, but that doesn't prevent stupid leaders from trying it!
When the government signs the pact it ceases to fund the X-COM
project... And when too many governments quit, Earth is doomed!

2.7 Dealing with alien bases on Earth
Those pesky aliens have established bases on Earth! Those bases
are well-hidden and only a prolonged patrol by X-COM crafts will
find them. You should send soldiers to take them out ASAP since
those act as infiltration centers. See 4.5 on how to find them
and 5.X for ground combat strategies.

base would be in the other area. As for others, check UFO activity
and see below.
