Squad Assault 4

Oh my gosh, I hate this one. Specifically the 2nd map (Roderick, Katarina, and Luke). I need help. I really want to beat it since it's the last one I have. I know there are a lot of free to play guides online, but I don't really want to put the effort into building those units. I'm wondering if someone can suggest a team with the units I have that would would. Here's a document with the list.

If you have any questions about the builds, just ask me. Also, I'd like to save Frederick, Reinhardt, Brave Lyn, and Priscilla if possible.

Thank you so much to anyone who helps!''

Edit: I realize I was a bit unclear. All I need help with is the second map, for now. I've got a team for the fist one. (Innes is boss)
