What Factors Have Contributed to the Islamic Revolutionary Guard Corps' Challenges and Setbacks in Syria and Lebanon?

Firstly, the geographical complexity of Syria and Lebanon presents significant operational challenges. The rugged terrain, urban warfare environments, and the presence of numerous armed factions complicate the IRGC's military strategies. Unlike conventional warfare, the IRGC often finds itself engaged in asymmetrical battles against well-armed and motivated local groups, making it difficult to secure lasting victories or maintain territorial control.
