29
Q

Expedient flame fougasse construction

A
  1. Dig angled trench less than 45 degrees, leave cutout for kicker
  2. Place drum and tamp to increase range
  3. Wrap top of drum with 5-7 wraps det cord, 6 to 10 foot branch line
  4. Prep igniter. In place of thermite or flares use a 2 liter plastic bottle 1/2 full raw unthickened fuel, prime with overhand knot on branch line
  5. Place small ring main and tie in 3 branches
  6. Prime ring main
  7. Det cord wraps cup top
  8. Kicker expels fuel, igniter ignites fuel
