Windows RTS realistic war strategy around 1999 [Sudden Strike]

[Maritimo]

I played this game as a child, between late 90s and early 20s. If I remember correctly I had this game on a demo disc.

The game was a fixed bird view style RTS set somewhere between WW2 and 2000s, entire map was densely built town and forests without any empty areas, there was no structure building in game. The game was realistic in a way there were no lasers or any high tech equipment.
What I clearly remember is the mission I played, you started with a bunch of paratroopers in north-east part of map, you could see the planes and animations of paratroopers dropping. South of you were enemy military defensive weapons who would kill your men on sight. West of you was a road going to nowhere in particular, but on south-west end of map was a bridge you could blow up.

Maybe something like Counter Action or Sudden Strike?

Yes! It's Sudden Strike. Thank you very much, I will surely play some of it out of nostalgia
