God I thought I would never be able to pass this part with just the Rainbow operators, this was the most difficult, I had to level up Iana, Ela, Doc and Fuze several times to be able to pass it and I still feel like I should level them up more but I don't have the resources for that, in the final part when I was only missing 3 enemies I started to panic 😱, of course the redeployment times ended and I had human shields to use, this stage can be passed using only the Rainbow Six operators, It will probably be easier if you have them all at E2 lvl max and m3 in all their skills, after this I am going to invest resources in finishing giving E2 to the ones I am missing and start giving them m3 while I level them up
