Rogue Spear was the last to have the classic planning and execution phases. Raven Shield had it, but it was usually not as rewarding to use, so I played it more like a hybrid of what R6 had been and current shooters of the time. I used to enjoy adjusting those plans and go codes and ROE to get my missions to go flawlessly in as little time as possible. Hit "GO" and 10 seconds later "mission accomplished."
I think Lockdown still paid lip service to it, but it was gone for the Vegas series.
