Bunker Breaking. Breeching the beaches help needed

[Steelwhip]

So I just started dipping my toes into Sealion. Working on doing one of the full campaigns but am running several test games before I settle into my 'official' playthrough.

The biggest issue I'm running into as the Germans are breaking those bunkers on the beach. Kinda hard to shoot at them when my troops dont have hard attack values. A scattering of armor and a few engineer troops, that seem to spend the first couple of turns clearing obstacles. Do I have to just sit on the beach and get my troops shot up waiting for heavier equipped troops to follow up behind..or is there some other trick to it that I'm not aware of
