How to use AT guns on the offense?

[HMCS Rosthern]

1. I place AT guns just behind and adjacent to my attacking forces. They can be used to maintain a supply line in case an enemy counter-attack attempts to isolate the attacking units. If an enemy counter-attack is successful and brings enemy units adjacent, the AT guns can get a few shots off.
2. AT guns are also useful for prying units out of bunkers, so you can use your armoured forces elsewhere.
3. Careful use of line of sight can help you get AT guns close. For example, use other units to block los.
