Which conflict served as a catalyst for militaries to recognize the need for immediate, on-site care for soldiers?

Answer

The Boer War

The Boer War in South Africa highlighted the critical gap between injury occurrence and definitive care, making it apparent that soldiers required immediate on-site medical attention while awaiting transport. This realization shifted the focus of military medical planning toward unit-level supplies that allowed soldiers or their peers to perform essential tasks like hemorrhage control and antisepsis.
