This is probally the best terran defence that I have ever had.
Each bunker has 3 marines and 1 firebat. and somewhare their is a ghost.
Hideing back in the base, is a dozed wraiths for air support.
This style of defences has held off a relentless assult from 1 terran and 2 zerg comps for well over 5 minutes!
Just repair FAST!!
