Maybe I am thinking of a different obstacle, perhaps a berm of some sort that was encountered at Normandy. I specifically recall seeing a documentary where allied tanks were being taken out going over longitudinal earthen/plant obstacles that was exposing the tanks underbelly to German Fire as the tank went over. The solution was for some tanks to be fitted with a plow like device that allowed them to punch through the object and create a hole through which other tanks could follow. Because the tank stayed horizontal the stronger frontal armour provided better protection than the thinner underbelly armour would have provided.
Whether or not the longitudinal earthen/plant obstacles were "Hedgerows" I am not sure.
That's a hedgerow in general.... 5 to 7 feet wide, 4 to 6 feet tall earthen berm topped by thick, nearly impassible vegetation. Several methods used to breach them, from the "salad fork" to punch holes in the berm in which explosives were placed to blow that section of the hedgerow, to several modifications to various armored (tanks) and construction (dozer) vehicles to climb the berm and bust through the vegetation.
Hedgerows varied in height, thickness, and difficulty. Solutions to get through then varied as well. No one standard in either case.
In game terms, it looks like breaches will be modeled ahead of time. Don't figure we will suddenly see the introduction of destroyable terrain into the maps.
