I don't spoil anything that you don't get out of the briefing.
I'm a "newbie." I gave the allies +25% more troops for this one. I was the Italians. I hid everything the first turn. My at guns started chirping enthuastically. I used the mortars to hit the matildas to try to immobilize them. I got a few of them and pounded them with guns until they got out. When the light stuff started coming I let my AT rifles join in. The Solothurn is a very nice AT rifle! I mostly wasted my artillery trying to walk it around. It scared them though. I used some mortars on their infantry. When my reinforcements came I foolishly got about half of it blown up. The "good" tanks I put behind the ridge which is right behind the trenchline. They were safe there and managed to hurt a truely large number of british infantry. Rommel's air support did very little, immobilizing a few troop carriers. Most of my AT guns were knocked out.
When some of his infantry approached the trenchlines on my left flank I had the men pour fire into the closest squads from about 150 yards. they took down the brits.
I managed to spook, blow up, or otherwise damage most of his tanks etc.
It was a tough battle, I'm not really sure why that Matildas weren't able to roll over me. I guess it was a proposition of my effective suppresion and damage to his infantry.
