White IrishKing:dont make marines till they at least have rpg. they are pretty useless without it. just play like forge at 1st and then when your attacking with tanks then start upgrading ODST. but dont just spam ODST, they are still pretty weak compared to other late game units. still use other units.

I would agree with you, except against early Anders. You need to make marines to deal with gremlins, rpg or not. If you're harassing with hogs and some gremlins pop out, run away, queue 6 marines from your ele and pel drop them in. Hit the front of their base with marines while running around the back with your hogs to check for a barracks, and potentially mac it. The marines, even with grenade, should fair well against the gremlins so long as this is still early game. After about4 minutes, you should be focussing on vehicles, or  marine upgrades.

This is when moving your elephant up will help. If you capture a forerunner supply hook, and Anders is pumping out gremlins, you're eco is flying by hers.
