Security forces and vehicles
A crucial element included as part of the advon team when deploying to a hostile area is typically security personnel. This ensures the safety and protection of the team and its equipment during the initial phase of deployment. Security personnel may include armed guards, military police, or specialized security contractors.
An ADVON (ADVance eschelON) team is a group of Airmen or Soldiers that are sent out in advance of the main body of troops to secure a base camp area and do the setup/prep work for the main group so that when everyone else arrives, the base camp is in place. Air Force ADVON teams are sometimes paired with Combat Controllers.
