Build LOTS of terminator assault squads take them out of your barracks, upgrade them to full strength and put them back in the barracks and/or orbital relay use a scout marine squad and infaltrate the enemy base. Then deep strike the terminators in to the enemy base. Build more as needed.
Space Marine assault tip
A great way to win as the space marines if you like terminators.
