Same principle as ATGuns just harder due to there longer effective range so you need to trail further back letting your infantry lead.
Infantry should at least spot any that fire, if your lucky they can provide the smoke screen.
If you have MGs get them in position otherwise the infantry are going to have to do the job with only long range vehicle support.
In some terrain I will also have a squad accompany the tank. He scouts for it making sure you don't blunder out & pops smoke if you get it wrong.
