I also received the last three rewards when I logged in today: Thank you!
With the 7.0 patch, I initially received mail with First Line, Strike Specialist*, Strike Commander*, and Led the Charge
Today received mail for Strike Hero, the Cutting Edge, and MK-90
*Note that I'd previously (years back) received the MK-85, Specialist, and Commander
For reference, I performed the PTS requirements as stated: i.e., completing the achievements only, not doing every KOTFE/KOTET Chapter, etc.
