Well.. this is a disgrace as I blanked out when I saw 1 marauder knocking at my doorstep at the early minutes into the game.

I was doing the standard 12rax 12gas reaper into reactor build when the marauder charged in immediately.. Well my first reaper was halfway into the opponents base but I pulled it back to defend with SCVs, but by that time he had 2-3 marauders which kited me whole day long with the concussion shells upgrade.

How do I defend again such thing, apart from scouting around my "possible enemy proxy locations" with my first reaper.

I tried building bunkers (x2) near my main CC, but my marines couldnt make it to the bunker

I was thinking after the game, should I have pulled about 8-10 SCVS and surround the first marauder until my marines are out?

do tell me your suggestions!
