breaching chages are used for walls and windos but you can breach fallers so that you can see were they are but you cant just blow the floor it will have some metal bars so you can only see a little bit trow the floor but this can make the deffenders sckeed.
breaching can be a good distraction so they think that you are coming that way but you are coming right behind them.
having a fuze would be good because he can fuze the place and then breach but dont do it if it is hostge.
