Answer:
brave and valorous
Step-by-step explanation:
According to Steinbeck, the bod of a soldier doesn't let them remember the extreme of emotions experienced in a battle. Steinback explains that a soldier does not remember what happened at the war. More worse the battle and more do they forget about it. During a war, the soldiers lose the instinct for self-preservation and hence they perform heroic deeds in battle.
Hence, when soldiers do not talk about their battle experiences they are considered to be brave and valorous.
