⇒ Combination is a way of selecting items from a collection where the order of selection does not matter
⇒ Permutation is an arrangement of objects in a definite order.
In other words:
⇒ Combination is when the order does not matter
⇒ Permutation is when the order matters

Now, let's look at the given information in the question
⇒ Need 7 players from a 12-person team
⇒ The purpose is to determine battle order
As it is stated in the question:

Since the order matters, thus, it should be [tex]\Large\boxed{\text {Permutation}}[/tex]
