Is assaulting Bunkers too hard ?

[wiggum]

I have to disagree here. A competent attacker seems to have a faster progress in the game both in Normandy and Kursk than in RL if playing a competent defender more often than the opposite. Especially is that seems true for the "bunker" scenarios, except possibly where severe lack of AT weapons making it difficult.
My view on this is more that you wouldn't be able to get all those 180 engineers into position in an attack against a fortified area against non disrupted/suppressed enemy. As the defenses are represented by fortified hexes and not my solid lines this is working as intended and as long as the bunkers are not disrupted they will hold the enemy of.

I agree that the hard part should be to get close to the bunkers, not taking them after you have surrounded them.

Currently ingame its the opposite. Its relatively easy to get close (adjacent hex) or behind the bunker but the assault, even with overwhelming forces against the 10 remaining defenders is a bit too hard (20 tries (reload) and fails every time). Mostly because a failed assault rarely results in the remaining defenders becoming Disrupted/Broken (which never seems to happen) or the "Finishing Off" rule does not apply (which would help in such situations).
