What were the advantages and disadvantages of grenades in World War 1?

Grenades in World War I offered the advantage of allowing soldiers to attack entrenched enemy positions from a distance, disrupting enemy formations and causing casualties without direct confrontation. They were portable and could be thrown into trenches or over obstacles, increasing tactical flexibility. However, their disadvantages included limited range, the risk of misthrowing or premature detonation, and the fact that soldiers often lacked training in their effective use. Additionally, the reliance on grenades could lead to shortages and logistical challenges in supplying the front lines.
