What are examples of metaphors and similes in Chapter 3 in All Quiet on The Western Front?

All Quiet on the Western Front was originally written in German by Erich Maria Remarque. In answering this question, I am using the Arthur Wesley Wheen translation, which gave the English-speaking world the iconic title.
In this part of the text, the story's protagonist, Paul Baumer, and his friends meet some younger soldiers who are less accustomed to the conditions at the Front. By comparison to these soldiers, our protagonists feel like "veterans." Accordingly, when Katczinsky shows the new men to a mysterious tub full of beef and beans, Katczinsky "plants himself in front of it like a general," a simile which indicates much about Katczinsky's personality and the dynamics at play. In terms of the dynamics of the group, indeed, Baumer describes Haie Westhus as "the executive arm, operating under Kat's orders," a metaphor which imagines the company as a large corporation in which Katczinsky is in charge.
Later, when a German aeroplane is seen falling out of the sky, Baumer describes it as "like a comet" as it "bursts into a streamer of smoke." This is a vivid simile which serves to illustrate, to those who have never seen it happen, how an aeroplane might look as it falls.
The "ordinary tommies" in the company feel that they have been "put through the mill and sent to the Front." This is a metaphor which is in common idiomatic usage: it suggests that the men feel as if they have been ground through the system like grist through a mill, like a product to be used by the government. The men who feel this way, we can infer, feel expendable. Other commonly used similes are applied to Haie Westhus when he "raised his arm like a signal mast and his hand like a coal shovel." These phrases give a clear depiction of his physical position.
