overview

Mammoth Sniper Challenge II is the second event in the annual Mammoth series. This is not a match; it's a crucible of physical punishment and sniper precision. Two-man teams must carry all gear, ruck over 35 miles, and engage in 11–14 stages with no support and no forgiveness.

‍

Run by G3 Dynamics, this challenge draws elite military units, LEOs, and seasoned civilians aiming to prove they can operate underweight, under stress, and under fire.

‍

  • Three-day, 72-hour sniper endurance match — no resets, no help
  • Stages out to 1,000+ yards, with pistol transitions, unknown distances, and simulated sniper hides
  • Toughman Division: Carry rifles, ammo, food, and shelter across 30+ miles
  • Sponsors: Vortex, MDT, Thunder Beast, PROOF Research, Kestrel Ballistics
  • Teams: 100 two-man squads — a mix of SOF, veterans, and top civilian shooters
  • Legacy: Now in its 15th year with dropout rates exceeding 60% on Day One

‍

Whether you're a SOF team sharpening your edge or a backcountry shooter chasing the hardest event in the sport, Mammoth II is built to break you.
