I really like how Geronimo is proposing breaching doors with a placed C4 charge, however I was wondering if it would be a worthy option to give players the choice between taking a C4 breacher, a sledgehammer or a 2-man operated battering ram, I imagine the ram only being effectively used in squads of 3 or more, however I would love to be able to just slam a door open for a squadmate and rush in behind taking corners with a shotgun, plus the battering ram could be a fun way to give a squad more things to work together to accomplish as I really appreciate the game's emphasis on teamwork and going in with buddies being tacticool together
I was also curious about how flexible the approaches to buildings might be, I really like the idea of making each building have multiple points of entry and different methods of entry, for example crawling into through little hole or smashed out window, dropping in from the roof, adding multiple approaches to missions could add a ton of replayability and openness for giving the players new challenges and ways to spice up a mission 😅
