I had an idea today that I'd like to try tomorrow (Thursday) - and it's a simple one.
We don't RTB between missions. That is to say, we need to plan to stay out in the field for each of the four operations that spawn in each mission.
I recognize there will be challenges with this approach, especially regarding the re-insertion of soldiers who are KIA on the battlefield. My thinking is that this would be a great challenge for a Logi squad; creating an FOB in a central area of the map, and then running the missions from there.
