You need to build a base in most of your missions. The first few
missions don't allow you to create a lot of structures, so where you
place them isn't that critical. In later missions, though, you'll
have dozens of buildings. If you don't plan where you put them,
you'll end up with a base that does more to help your enemy beat you
than the reverse.
So, where do you place your structures?
Buildings that create units for you, meaning the Barracks and the War
Factory, need to be placed up front in your base÷where they can send
out units quickly. Because these structures create your army, they
must be in position to send new troops directly to the front line.
Nothing's worse than creating a new, desperately needed unit you
could use to fight back a powerful enemy attack only to have it
stuck in the back of your base.
Along the same lines, place a Service Depot up front, where
your units can access it easily. Because your War Miners and Chrono
Miners constantly move in and out of your base, also place your
Refinery in front.
Structures in Back
Several structures, particularly your power supplies and special
weapons, are either extremely vulnerable to attack or are targets
for enemy attacks. These must be kept in the back of your base, away
from a direct path from the enemy. Although your first Tesla Reactor
or Power Plant probably will be placed up front to be near your
first structures, place later ones well behind your other buildings.
Your power supply is vital to the health of your base because most
of your base defenses rely on it. Keep them behind your other
structures so enemies can't target them.
This is especially true for the Soviet Nuclear Reactor; this
massive structure is not only easily destroyed, it draws attention
to your base when you build it. At the very least, place this
structure as far away from your Barracks as possible. Special
weapons, like the Weather Control Device or Nuclear Missile Silo,
are targets for your enemies. Placing one of these structures at the
front of your base is an invitation for your enemies to eliminate it
