Are trenches still used in wars today?

While traditional trench warfare as seen in World War I is largely obsolete, modern military operations sometimes employ trench-like fortifications for defense in specific contexts, such as in urban warfare or in regions with prolonged conflicts. However, contemporary warfare typically relies more on mobility, technology, and airpower rather than static positions. Innovations in warfare have shifted the focus towards maneuverability and rapid response rather than entrenched positions.
