Analyze three quotes from chapter 5 in All Quiet on the Western Front.

The opening of chapter five in All Quiet on the Western Front reveals the daily difficulties that soldiers on the front had to encounter.  It represents yet one more aspect of life for which Paul and his fellow soldiers were not prepared:

Killing each separate louse is a tedious business when a man has hundreds. The little beasts are hard and the everlasting cracking with one's fingernails very soon becomes wearisome. So Tjaden has rigged up the lid of a boot-polish tin with a piece of wire over the lighted stump of a candle. The lice are simply thrown into this little pan. Crack! and they're done for.

Earlier in the narrative, Paul talked about how the young soldiers were told that they had to serve out of patriotic duty.  However, such words rang hollow when the recruits were put on the front line.  This is communicated in realities such as battling lice.  The young men must fight everyone and everything as part of their time on the front. Opposing soldiers, animals, and even lice posed a challenge.  The way Tjaden comes up with a way to kill lice is reflective of the struggle that young soldiers faced in war, something that never leaves Paul's thinking.

One reality that was never communicated to the soldiers was how much they would miss home.  Young people signed up for the war under the belief that it would be quick.  They were filled with visions of returning home as conquering heroes.  As chapter five unfolds, it is clear that missing home is taking a toll on the young soldiers:

Haie looks at him sadly and is silent. His thoughts still linger over the clear evenings in autumn, the Sundays in the heather, the village bells, the afternoons and evenings with the servant girls, the fried bacon and barley, the care-free hours in the ale-house-- He can't part with all these dreams so abruptly; he merely growls: "What silly questions you do ask."

Haie's memories of the life he once lived brings out an added dimension to war's pain.  The quote captures an ache that soldiers felt.  As Paul details, the war will forever change the soldiers who fought in it.  They will either die on the battlefield or return unable to adjust to their world.  As Haie's "thoughts still linger" on his past, it becomes clear that he will never be "care-free."  This is why he growls and cuts off his recollections.  He knows that he will never be able to find the happiness that was once there.  He will never be able to soothe the ache of yearning for how things used to be.

Paul and the other soldiers realize that their experiences on the front do not compare to what they were told in school.  They received a theoretical instruction that failed to account for the war's brutal reality:

We remember mighty little of all that rubbish. Anyway, it has never been the slightest use to us. At school nobody ever taught us how to light a cigarette in a storm of rain, nor how a fire could be made with wet wood--nor that it is best to stick a bayonet in the belly because there it doesn't get jammed, as it does in the ribs.

Paul speaks honestly about how "mighty little of all that rubbish" resonates with the soldiers who are at the front. The war has taught the men that what was told to them in institutions such as school has little connection to war's reality.  It never prepared them for what they were to face.  This only adds to their disillusionment.  It shows how the war inflicted emotional and physical wounds.
