Largely depends on if you're willing to deal with it or not.
One of my favorite games is S.T.A.L.K.E.R Shadow of Chernobyl which is likewise a very realistic game. You die very quickly, if you get shot you begin to bleed out, your guns decay overtime and jam if you don't repair them, etc. What I like about all of it was the dev team didn't implement all those features just because they wanted the game to be hard. They implemented those features because it all adds to the premise that the main character is not the core focus of the story. Indeed a big aspect of SoC is how the main character of the game is arguably the world you explore, and the player character is just the one who observes it.
With S.T.A.L.K.E.R it also has multiple difficulties, and I always found the easiest difficulty lacked this connection with the player. Which is why I play it on "Master" difficulty mostly because I want to die in a few shots and feel this tension throughout the game that hey "I might die soon". It means the story has more consequence and you are more involved as a result.
However that's a singleplayer game released back in '07. Red Orchestra is not the best series, and I don't think this particular framework works particularly well for a multiplayer game. Even Counter Strike, despite being fairly realistic in terms of damages itself, still has you potentially absorb dozens of bullets and multiple gunshots to the face depending on the weapon.
