Infantry is most often seen as being more than a little bit stronger than Tank, Tank having only expensive MiGs to counter your units, which can't easily be replaced as the game gets closer to an end.
You've also got Nuke Cannons that can obliterate his units, along with a bomber at 3 stars instead of 5.
As inf, if you don't have too many actions to perform in the moment and want to fill an outpost or a troopcrawler, take the time to evac your unit beforehand so they get the horde bonus. Same goes for lix.
A good way of dealing with migs as inf is to fill a few minigunners in your outposts and build more ecm to support them. Unless you are very rich, prefer to build troopcrawlers as your minigunners source as it's more cost efficient, then evac some of the gunners and put them in the outposts. That way your opponent won't know what to target and lose migs whenever he try to use them.
You can be even more sneaky and bait the migs somewhere while you have immobile stealth outposts filled with mini gunners on their way ready to intercept them.
Beside you played decent. You just seemed a bit slow to notice when your trucks got killed and to spend your money the first minutes.
Was still a pretty comfortable win for you, not that close really, but tank indeed did a good job at giving you a fight considering the matchup.
