GPS Denial Over a Capital Region.

GPS goes unreliable across a metro area in the middle of a normal Tuesday. Pick a seat, take five injects, make the calls — and see what each one costs, drawn from real incidents. Fifteen minutes, no login, printable debrief.

Self-guided discussion exercise · ~15 minutes · no login

Pick your seat.

Five injects from the facilitated scenario, one real call at each. The map is your common operating picture. No score, no timer — just consequences, drawn from the public record.

All four seats share the same five injects — your lane, your hotwash, and your AAR change with the chair. Worth one replay, not four.

Exercise objectives
  1. Examine cross-sector information fusion and incident coordination in the first hours of an unattributed interference event.
  2. Assess awareness of PNT holdover limits and the graceful-degradation decision when timing can't be trusted.
  3. Discuss pre-attribution public communication — what officials say before anyone knows the cause.
Ground rules
  • This is an open, low-stress, no-fault environment. Disagreement with our consequence notes is expected — that's discussion.
  • Respond from your organization's actual current plans and capabilities, not the ones you wish existed.
  • Your choices are not precedent-setting and may not reflect your organization's final position.
  • There are no hidden materials and no trick options.
  • Identifying problems matters less than what you'd do about them — problem-solving is the focus.
Assumptions & artificialities
  • The region and scenario are entirely fictitious; no real jurisdiction is depicted.
  • The scenario is plausible, and events occur as presented.
  • Assume other entities cooperate in good faith unless an inject says otherwise.
▸ About this exercise — type, scope, and what it doesn’t do

Type: a self-guided, discussion-based exercise modeled on a facilitated tabletop. In strict HSEEP terms (HSEEP is the U.S. government’s standard for emergency-management exercises), a branching web exercise sits closer to a “game” than a tabletop — we say so because precision about exercise types is part of doing this credibly.

Scope: one scenario, one seat at a time, five injects, policy- and coordination-level decisions only, ~15 minutes. Your choices and notes stay on your device.

What it doesn’t do: evaluate your organization (no evaluators, no Exercise Evaluation Guides), exercise your actual plans, or replace group discussion — the parts of HSEEP practice that need a room. The facilitated version runs with a facilitator, evaluators, a proper hotwash, and a jointly written AAR/IP.

What it deliberately isn’t: there is no score, because discussion exercises are examined, never graded — that’s doctrine, not modesty. No countdown timer, because tabletops are low-stress by design; the scenario clock supplies the urgency. And no “how other players chose” statistics, because this page runs no tracking — your comparison group is the documented public record each consequence cites, not a crowd.

Want that version — your colleagues, your sector’s plans on the table, a facilitator pushing back? See formats and pricing — pilots run 90 minutes, $5K–$20K, and you keep the after-action report.
