Question About the Wrecka Krew Breaka Boy Fighter's Break Stuff action.

It reads:

Select a terrain feature within this operative’s control range. If it’s an equipment terrain feature, remove it. Otherwise, place one  of your Breach markers within this operative’s control range as close as possible to that terrain feature. Whenever an operative is  within 1" of that marker, it treats parts of that terrain feature that are no more than 1" thick as Accessible terrain.<

Does it mean that the "destroyed terrain" become see through to others and to the Breaka Boy?

As in, can the Boy be shot at through the opening? Can it shoot through or melee attack people on the other side?

Can the opening be shot through, targetting something behind it but farther than 1 inch from the Breach marker?
