Your objective: Assess containment options while reducing nuclear escalation risk and noting uncertainty.
Guest practice lasts for this visit and is not saved to an account. Simulation performance is not academic mastery. Written reasoning awaits teacher review.
A crisis briefing contains incomplete and conflicting Cold War intelligence.
October 1962: reconnaissance photographs identify Soviet missile sites in Cuba. Kennedy announces a naval quarantine on October 22 while advisers debate air strikes and invasion. On October 28, Khrushchev agrees to remove the missiles; U.S. assurances and a private understanding about missiles in Turkey help resolve the crisis.
Instructional simulation: distinguish supplied scenario evidence from historical fact. TEKS: US.8(A)

INTELLIGENCE HEADQUARTERS · SIGNAL CONTROL
Curator Morgan: “A dramatic signal is not automatically a reliable one. Inspect it before you send it.”
Fictional training network set within the Cold War mission. Packets paraphrase this mission’s teaching scenario; they are not reproductions of historical documents.
Learning goal: evaluate a source’s origin and limits, corroborate uncertain claims, and explain an escalation risk.
Morgan · lead analyst 1/3
Welcome to the command room. Your job is to separate a documented fact from an inference, then recommend a response that accounts for uncertainty.
Select a numbered station to investigate. Move your analyst marker with the direction pad, or focus the room and use arrows/WASD; E interacts. You can also click the scene to move. No time limit.
Explore the room. Morgan can model the skill before you begin.
Success means correctly classifying all three records, staffing verification and diplomacy, and testing a qualified response. Visiting stations alone does not complete the investigation.
Inspection records where you have looked, not what you have learned. Correct routes and a sustainable response are required; explain the evidence, uncertainty, and escalation risk in your report. These milestones are not a grade. Use “Save investigation checkpoint” to keep your work when signed in.
In October 1962, U.S. reconnaissance identified Soviet missile installations in Cuba. Kennedy announced a naval quarantine on October 22. On October 28, Khrushchev agreed to remove the missiles. U.S. non-invasion assurances and a private understanding concerning U.S. missiles in Turkey contributed to the resolution.
Morgan, Reyes, this command room, the three training packets, staffing numbers, and branching responses are fictional. The cinematic room artwork is reused from this mission’s authored introduction; it is not a historical photograph. Numbered markers locate the training stations, not real archival objects. The ambiguous practice image is not the actual reconnaissance photograph that identified missile sites. Player choices do not rewrite the historical outcome. This room uses a radio/diplomatic channel, not the later Washington–Moscow hotline.

The sender and date have been authenticated. The cable confirms a diplomatic standoff. It contains no order to launch an attack.
Analyst’s question: What can this document establish without adding a claim it does not contain?
The packet enters at the left of row 3. Tap a router or press Enter/Space to turn its arrow clockwise. Arrow keys move focus. Send the packet to a desk at the right edge: row 1 = Verified record; row 3 = Needs corroboration; row 5 = Unverified claim. Damaged routers block signals. Maximum 18 hops.
Inspect the packet. Rotate routers to send it to the desk its evidence supports.
After classifying the signals, allocate up to 30 fictional team-days. Each workstream needs at least 8. Verification cannot replace image analysis or a diplomatic channel.
Next: route all three evidence packets correctly.
No countdown and no mastery points for speed. Route mistakes are recoverable. Saving the mission report stores these routes and team allocations; unsaved edits are temporary. / Sin límite de tiempo. Guarda el informe de la misión para conservar tu progreso.
LIVE PLANNING WORKSPACE
Build a plan using the briefing. Then test whether it survives a funding reduction. This is an instructional model, not a prediction of real events.
01 / INVESTIGATE
Read an evidence card below, then choose “Use this evidence” to support your plan. Reading a card does not select it. You can use one main source at a time; choosing another replaces it.
No evidence selected yet. Read a card, then choose “Use this evidence”.
02 / CHOOSE A PLAN
Choose a plan, then adjust its scale. The budget below updates as you make changes.
03 / TEST & EXPLAIN · Use the headquarters above to inspect and route the evidence and allocate your team. Then write your analysis below and choose “Run simulation and show consequences”. Review the results and save your report. Academic mastery requires 80% on the separate check.
Choose your evidence and plan above, adjust the workstation controls, and explain your decision. Running the simulation shows consequences; use “Save mission report” afterward to save your completed runs.
START SMALL · FIELD TRAINING
New to this? Start with one idea, see it in action, then try it. Hints and retries are unlimited. Practice stays in this visit and is not saved or graded.
A source is a record from a particular time and perspective. First identify what the record actually says. A classroom resource model can explore tradeoffs, but its numbers are not historical measurements.
October 1962: reconnaissance photographs identify Soviet missile sites in Cuba. Kennedy announces a naval quarantine on October 22 while advisers debate air strikes and invasion. On October 28, Khrushchev agrees to remove the missiles; U.S. assurances and a private understanding about missiles in Turkey help resolve the crisis.
Find one specific quantity or statement. What does it tell you, and what does it leave unknown?
Confirms a standoff but does not establish an attack order.
This is supplied classroom evidence. A reliable source can support a limited statement, not every possible conclusion.
MASTERITRAIL · MISSION BRIEFING
Sound starts only when you press Play. The mission opens when the intro ends.
October, nineteen sixty-two. The world is on the brink. Your mission: examine the evidence, separate fact from rumor, and advise a response. Every choice carries consequences. Analyst, take your station.
Historical setting: the Cuban Missile Crisis. The mission is an instructional simulation.
