Dudes have to be well prepared, equipped, have solid Intel and the tanker has to either be stupid or have bad leadership.
The tanks should keep their distance and support infantry while keeping a look out on thermal for anything that gets too close. They have emergency features like trophy (it’s a explosion that shoots down missiles) but mostly they wait for infantry to find targets for them to blow up.
In tank-tank combat they often let their infantry fall back while they lock on at range and hope their gunnery is better.
