What tactics did the two armies use to try to break the stalemate?

To break the stalemate, both armies employed a combination of tactics including the use of artillery bombardments to weaken enemy positions before launching infantry assaults. They also engaged in trench warfare, attempting to outflank or infiltrate enemy lines through surprise attacks and raids. Additionally, both sides experimented with new technologies, such as tanks and aircraft, to gain a tactical advantage and disrupt established defensive positions. Finally, they often resorted to attrition, aiming to wear down the enemy's manpower and resources over time.
