  • Plywood.
  • Chicken wire (optional).
  • Burlap or canvas (optional).
  • Small saplings, stripped and lashed together in place of pipe or fiberglass rods.
  FINISHED SUBSURFACE SITE
  G-4. The team generally uses finished subsurface sites for stay-behind missions and when they
  anticipate having to remain underground for extended periods of time.
  LOCATION
  G-5. Dig the site in a well-concealed area, away from enemy observation, and well away from any
  populated areas.
  CONSTRUCTION
  G-6. Use any available containers, such as rucksacks, sandbags, or socks, to remove the dirt. Some of
  the removed soil will later be placed on top of the site. Leftover dirt must also be camouflaged.
  Overhead Cover
  G-7. Overhead cover is constructed strong enough that it can be walked on.
  Ingress and Egress
  G-8. Construct two sets of entrances and exits, primary and secondary (emergency), and cover and
  conceal each.
  Size of Site
  G-9. The site must accommodate the whole team. It must allow freedom of movement and have room
  for separate and comfortable sleeping positions.
  Materials
  G-10. Materials needed depends on the design.
  • Fifty 2 x 4 x 12's (2 inches by 4 inches by 12 feet boards).
  • Six 4 x 4 x 6's (4 inches by 4 inches by 6 feet boards).
  • Sufficient gravel to cover the floor.
  • Eighteen inches of cover over entire site.
  • Backhoe or Soldiers with shovels.
  • Sandbags, 100 each.
  • One large general-purpose tent to cover construction until complete.
  ADVANTAGES OF SUBSURFACE SITES
  • Little risk of compromise.
  • Protection from artillery and small-arms weapons fire.
  • Protection from nuclear attack.
  • Excellent camouflage.
