This may be a stupid question, but I've only been playing SC2 awhile, so dunno much, i'm curious what's the best thing that i can do to complement early marine harass, or early MM?

Would going for siege tanks affect my rush by delaying it abit? How about MMM?

I know reply'll be scout, but just want to pick your brains and try to find out what's your experience with this. Thanks!

Ah, sorry, I meant for each matchup, what would be best? According to what I've experimented with a bit, TvP is to rush as early as possible without building up too much, sometimes I just go with only a few marines and SCVs, TvZ the same, but with more Marauders generally, TvT have to build up even more, usually I have to hold off against a rush first before attacking. Is that correct?
