Short Promare Gueimei theory
While watching the movie for the 5257th time, I noticed that, when Freeze force found the secret burnish camp in the volcanos and that, in order to protect him, Meis and Guiera sent Lio in another volcano right before getting shot by ice cubs, Guiera was falling on the ground first.
Maybe it's just a simple detail but Meis and Guiera were standing next to each other and it would have made sence to have the both of them falling at the exact same moment and in vertical position.
However, Guiera fell first and Meis fell on top of him.
My theory is that, right after Lio was ejected and that they both realized that the fire wall they were protecting themselves with was about to collaps, the both knew that it was the end for the both of them and that Freeze force was going to get them no matter what.
If Guiera fell first, it was because he decided to step in front of Meis after the wall collasped (there is a very short times between the fall of the wall and the moment Vulcan shoots) to protect him from the ice bullets.
Miami being way larger than Dallas, he might have though that it will take more time for the armure to be frozen and so, might have give Dallas hopeless seconds to find a plan or runaway.
Or, they both knew that they were done for but Guiera still decided to step between Meis and the guns simply to protect him as an act of sacrifice ? Love ? (definitly love lol).
It explains why his body fell first and was then covered by Meis' own body later on.
Also, in the ice cub, Meis seems surprise ? As if he wasn't expecting Guiera to step in front of him to be used as a shield while Guiera simply looks angry or scared but definitly not surprised like Meis
