Ok thanks for that reply. Its helpful.
One of my players was hit by both a missile and a thermal detonator. He managed to survive, after a comrade healed his bleeding out crit. This was a narrative situation mostly where I ruled his armor was damaged 2 steps which inferred a -1 Soak Value, inoperable electronics/optics and no longer sealable in a vacuum etc.
This made sense as the armor was torn open, being the only barrier between the blast and his own fleshy body.
