But yes, it is still risky but effective business to attack a tank...
Best tactic for infantry is to charge with the 1st action, then move back into cover with the 2nd action.
If the tank tries to take a charge action against them in his next turn they can react after the tanks move.

it may make the Reaction after the target models have
moved but before any Close Combat dice are rolled."
