AIM-9 Sidewinder: to keep the russian jets in close proxmity under threat

AIM-120 AMRAAM: A stand off weapon. Spot the enemy in the radar and hit him before you see them.

They both are more than enough to score some heavy hits on the Russian jets. I will be surprised if this ever becomes an equal fight. Russian pilots are still not fully tested. Once the f16s get there, they will know the difference.
