"Escape to Salvation" - "Magnificent Retreat" [Campaign 4, Mission 4]

Damn, if they had said that Frida would be fighting, I wouldn't have developed her at all; she's only level 20! I did pretty well with Wulf, but that Chaos faction guy really annoyed me with his summoning! I'll have to start the mission where Frida is again. Is it possible to develop her fully there?
