Adding 501st to Military Might Assault Battle

I'm stuck on the last mythic tier. not going to be able to beat it at all. But I did find Cody's zeta useful. My strategy is

Put Cody lead for his protection recovery on all clones. Whenever fives or echo attack out of turn they still recover protection(not sure why). And if fives is taunting everyone has time to recover their protection till the last phase(make sure he's beefed up on defense n tenacity mods) Which might be the hardest part assuming u have five's tactical awareness

Only have relics on fives and rex everyone else is still g12. For those in the lower tier I was able to do a similar similar strategy, hope this helps
