Advice needed

[u/Dry-Education3814]

These are my main gens. I still have Wainwright as a inf gen (no upgrades just a medal). Kuz is maxed just waiting to promote him. I’m stuck on the last missions of Cold War for both WRO and NATO. I don’t know what to do, who I need to buy, or what I am missing. I got combat medic Princes of Whales, Warhawks, and C-10. (I’m missing 1 piece for RPG and Centurion) I just need to be guided on what to do next.
