Name Those Characters - Senjō no Valkyria

One of my favorite images from Senjō no Valkyria, a series I would really like to see get licensed for R1 release.

First person to e-mail me correctly naming the three characters (full names please) AND which platoon they belong to wins a $5 RACS gift code:

Good luck!

UPDATE: Ichben got it first with Gallia- 7th platoon: Alicia Melchiott & Welkin Gunther & Gallian Militia- 1st Platoon: Faldio Landzaat. Thanks to everyone who sent in their answer!
