Just did the Rank 18 for Gold Eagle - it is a solo Defense mission. I had no idea what it was going to be so I brought along Volt (all arounder - good for defense, offense and mobility missions). Good thing I did, too! You defend a pod against corpus invaders, for 5 waves. You have 3 revives, too. I lost two of those revives and got the rank up killing the last guy on wave 5 just as he was killing me, and the pod had just  a fraction of health left. My corpse fell to the ground as the 'mission success' screen came up. To my great relief, the next screen confirmed that I did in fact pass and am now a Gold Eagle.

My recommendation: bring Frost (or Volt) and a lot of energy refills, spam shields and level 4 radial damage attacks.
