Islam didn't exactly have "religious military tactics".
It did have many "rules of engagement", that can be generally summarized in "Don't harm people who can't, or don't want to fight back", but for actual military tactics, there are some broad advises, staying brave and united in battle, preparing whatever force you can to face the enemy, etc. Such things obviously apply today and across all history.
That said, there are some interesting tactics that Muslims came up with, there are many examples, some in the "Sunna", during the life of the Prophet, and some in the many centuries after that. But these are tactics Muslims used, not "Religious tactics". Some useful and relevant morals can be extracted out of them though.
