The key, as J2D pointed out, is combined arms. Use infantry to get close enough to ID the infantry in the trenches. Then you can area fire the location. Once they are taking hits you can move your tanks closer to where they can do direct fire but that's taking a chance. Once the infantry starts taking damage you can move your own infantry closer.
Without an infantry screen you can area fire a section of trench for a bit, until you feel cocky enough to advance, then move a single vehicle forward to see what they can see.
Any tank will overrun an ATG if it gets close enough. Any movement order will cause the destruction.
Tanks will not destroy infantry simply by moving over them like they do guns.
Taking infantry out of houses is the hardest thing to do in the game, as it is in real life. Use the same formula as for the trenches, lots of fire, suppress or damage the enemy units then move closer with your own infantry and attack at close assault ranges. If all you have are AFV's this task is extremely difficult and dangerous. Firepower and more firepower is all that works.
