Looking for some good Gun/Military based anime

Recently I've been on a little bit of a tactical mil-sim binge, and I realised that there's very little anime that I've watched that fit that bill. All of it is either swords and magic, or sci-fi laser rifles and mechs.

Are there any shows that have a focus on contemporary weapons and combat? It doesn't necessarily have to be a military show, so long so as the main method of combat is gunplay. Non-anime examples of what i'm looking for would be things like the John Wick movies, or the Escape From Tarkov: Raid series.

Two shows I've already watched and really enjoyed was Lycoris Recoil and Black Lagoon. Are there any others that you would recommend?
