any tips for assaulting artillery/emplaced guns

[awoodby]

Hello,

Still going. Just got to first German singleplayer mission, the emplaced artillery chews me up (not to mention incoming tanks)

I understand angle of attack, ie hit the sherman in the side (though it won't LET you), and did finish this mission by swamping the defenses...

but I'd LOVE to be able to take them out without such losses, any tips?

Thanks!
