He's a sergeant who says this about an officer in front of an officer, he gets 'called out for it' in the sense of JRPG teenage friends calling each other oafs, but not in any kind of professional sense. The officer he then tries to flirt with just apparently brushes him off off-screen, but it's weird how they all think Claude is wonderful yet he has no control over or respect from his NCOs. It's a weird kind of army that evokes the gravity of a WWII-era military fighting for it's existence in a daring all-or-nothing campaign with people dying by the thousand on one hand and anime high school antics that ignores how militaries actually work on the other. Raz is ticking the 'comedy sex pest' box from the grand list of anime/JRPG tropes, but following VC1 it just feels a bit odd for a Darcsen sergeant who would surely need to be a bit more careful when it wouldn't take much for an officer to wreck his life. It's like the main plot is taken from a war film but the squad dynamic taken from a teen comedy, it just feels a bit odd to me.
One thing I did like about Raz is that his friendship with the sniper where she keeps him out of trouble is an echo of their battlefield roles where his job as a shocktroop leader is to be up close and aggressive and hers is suppressing fire to cover him.
To be fair, the army in this world isn't a one on one represantation of modern militaries to begin with. The whole federation army seems to barely hold together and they don't seem have that long of a training for recruits to begin with. For all we know the 2 europan wars that happened in this world so far could be the first ones where there actually is a more sophisticated hierarchy. Plus the whole group were friends before entering the army so they don't have a classic officer-soldier relationship anyway.
