While some early Close Air Support had been attempted and met with success in Nicaragua during the Interwar period, there was very little doctrine other than defining requirements and no structured development was completed prior to WWII. During Guadalcanal, Air Liaison Parties (ALPs) were improvised, trained on the island, and would only occasionally visit the front lines to observe targets. On New Georgia, the ALPs began briefing a day prior to action, offering occasional improvements.
