Answer 1

Answer:

Night combat is combat that occurs during the hours of darkness. It is distinguished from daytime combat by lower visibility and its reversed relation to the Circadian cycle. Typically combat at night is favorable to the attacker, with offensive tactics being focused on exploiting the advantages to maximum effect.[1][2] Defensive night tactics mainly focus on negating the advantages given by the night to the attacker.[3]
