What is the difference between regular war and total war?

Regular war involves conventional military engagements between nations or groups, typically characterized by established rules of engagement and limited objectives. Total war, on the other hand, encompasses a complete mobilization of society's resources and often blurs the lines between combatants and civilians, aiming for the total defeat of the enemy. In total war, the entire economy, infrastructure, and civilian population may be targeted to achieve victory, leading to more extensive destruction and loss of life.
