What she means:
in the first season of Skam, Isak is told by his best friend that "he only knows gay songs", and then when we get to know him again in season 3 we find out he nowadays listens to music that makes him feel tough. That that's the specific reason for it. We get a deep insight into this image of heterosexuality he's trying to project, and that dissonance in characterization makes it clear that it's something he's forcefully constructed in the last year. There are many more explicit examples of his internalized homophobia, but this one strikes me as especially heartbreaking because it's a direct response to something that was meant to be a casual remark, but had a deep impact on shaping his self image.
Colourized footage showing the dramatic efforts to store, and move the large volume of shells needed at the Verdun Front.
Using over 10,000 shells during an major attack was expected, over 20,000 common. The Germans in preparation for this battle made special arrangements to maintain a high rate of artillery-fire during the offensive.
33 1⁄2 munitions trains per day were to deliver ammunition sufficient for 2,000,000 rounds to be fired in the first six days and another 2,000,000 shells in the next twelve.
