Discipline/Military Protocol in Senjou no Valkyria

I recently discovered that Senjou no Valkyria had an anime adaptation, and have just finished watching the first five episodes of the show. So far, I am finding the adaptation enjoyable, and quite close to the game in terms of tone and plot.

However, I am reminded of a question that frequently bothered me throughout my play-throughs of the game: For an ostensibly military force, why is the Militia's discipline so incredibly lacking? A major early plot point is the refusal by the senior noncoms (Largo and Rosie) to obey their new lieutenant (Welkin), as well as a refusal to serve with an ethnic minority Darcsen (Isara). To acquire their compliance, Welkin chooses to make a gamble based on the outcome of the next day's operation, which proves successful. My question is, however, why there seems to be no response or discipline enforced against the two noncoms, who by refusing to follow their officer arguably committed mutiny, and almost certainly could be found to be derelict in the execution of their duties.

Strangely enough, this trend doesn't seem entirely confined to the Gallian militia. During the repulse of General Damon's failed attack on the Imperial supply route through the forest in episode 4, one of the under-officers in the Imperial Army questions General Gregor's orders to his face. This seems like a sign of some sort of major breakdown in discipline within the Imperial command structure, yet Gregor seems to find it unremarkable and doesn't enforce discipline on the officer in any way obvious.

Finally, it seems that the Gallian armed forces have been coed for a long time, since Captain Varrot is a veteran of the previous war, and nobody finds the presence of a sizable body of female soldiery in the Militia worth note. That said, Faldio (a junior officer) commits multiple acts of sexual harassment throughout episodes 4 and 5 against Alicia, a noncom. This seems like a severe breach of some sort of fraternization regulation, and certainly a court martial-able offense. How do you feel that Faldio's content fits into what appears to be a well-regulated armed force?
