Step-by-step explanation:
Poor tactical decision-making: One of the primary reasons for the high casualty rates during trench warfare was the lack of effective tactics. The decision to launch frontal assaults on well-defended enemy positions resulted in massive losses for both sides. The commanders often failed to adapt to the changing battlefield conditions and continued to use outdated tactics that were ineffective against the enemy's defenses.
Inadequate training and equipment: Many soldiers were ill-equipped and inadequately trained for the harsh conditions of trench warfare. The soldiers often lacked proper protective gear, and their weapons were not always suited to the challenges of trench warfare. In many cases, soldiers were also poorly trained in the use of their equipment and tactics, which increased the likelihood of making fatal mistakes.
Poor living conditions: Living conditions in the trenches were terrible, with soldiers often exposed to harsh weather conditions, disease, and unsanitary living conditions. These conditions weakened the soldiers physically and mentally, making them more vulnerable to illnesses and mental breakdowns. Soldiers who were ill or exhausted were less effective in combat, making them more likely to be killed or injured
