More tools can't hurt, and I think this is more for the aspect of communication without using a mic for co-op gameplay. But from a realism perspective I doubt a SWAT team would use this much.
Thanks for your feedback. I like to think these things will provide some use but ultimately help new players understand some levels better than others, as well as give players who wish to use it an opportunity to communicate plans a little better. From a realism perspective, they keep it pretty high level and yeah, just talk about entries and any known threats. A lot of this will be covered in our briefings, so this just acts as another tool in the belt for people who wanna use it.
