What is the name of the Ps4 or PC game?

I'm looking for a game. Seen a long time ago, when it comes to war. However, the game is very mature and very tactical. You can, and that's what makes this game so special, switch from a first person perspective to a tactical perspective and view almost everything from an excellent angle from above, thus continuing the operation from above. The way you like it. Can someone tell me what the game is called?

I think you mean operation flashpoint from 2001
