Albeit I personally like Bardia, I do agree some barbed wire along the river, or harder to get up the sides of the cliff, and replacements of the 88s would do wonders. One watching the north road/bridge easier would be perfect, maybe in the dock area, and possibly better placement on the Western/southern road. Sure it would be difficult for the tanks, but it makes infantry more important, rather than having a matilda just camp around.
