If you're fighting a rifleblob and they throw down a few hundred munis in zooks, just park your vehicles away in a defensive role. Use your tank(s) to keep squads from capping your flanks.
If those zooks are your opponents main source of AT, their blob is all they have. If they run out to the flanks with it, you just run away while gaining the map advantage. If he stays put, you've contained the blob and likewise gain the map advantage. Plus a contained blob is much easier to blow up with indirect fire.
this is why all factions need demo charges imo
your blob gets blown a few times you learn to stop blobbing....(free weekend with the goliath was rifle blob hell...glorious freedom gibs all over )
