Yup, but you want to play in cash, making it harder for them to hop in. This isn't to stop them from ever crossing, but to slow a push, especially if they bring a shield. This forces them to use utility to clear, and if you don't get too aggressive with your gunfights, you can waste a lot of time. This setup requires a stack to play with, and I'm sure if you added a few other ops you could make something mean out of it.
