A reliable source can be wrong, and an unreliable source can report something true. Treating those as the same question makes intelligence too easy to flatten into a single die roll or a single label.

Source Reliability uses two ratings. Reliability describes the source's record, access, and incentives. Information Confidence describes how well the specific report is supported. Rate both, then tell the players what their agents can reasonably conclude. The procedure creates uncertainty the group can investigate instead of hiding the answer behind the screen.

An operation gets easier to design once its purpose can be stated in one sentence. Surveillance, liaison, recovery, verification, protection, and disruption create different pressures even when they use the same characters, locations, and opposition.

Mission Types gives the Game Master 20 operational frames with a clear objective, a useful source of pressure, and a concrete success condition. Pick one frame, add a target and setting, then decide what changes if the agents succeed or fail. The result is enough to turn a vague assignment into a playable mission.

A useful mission seed creates a question, a deadline, and a reason the agents have to become involved. It leaves the method open. The same problem can support research, surveillance, liaison, protection, recovery, or counterintelligence depending on who assigns it and what the group discovers.

These 20 seeds use fictional organizations, locations, and events so they can drop into government, military, police, corporate, journalistic, or independent campaigns. Pick the premise, choose a Mission Type, and decide which fact in the opening brief is incomplete. The rest can emerge through play.

A mission can be sound and still go wrong in ways nobody planned for. The useful complication is the one that changes a decision: time becomes scarce, access narrows, a source becomes uncertain, or the team learns that the original intelligence picture was incomplete.

Mission Complications supplies 20 pressures that can enter before play or appear after a setback. Roll once, choose the result that fits, or combine two when a mission needs a harder turn. Each complication changes the situation without dictating how the agents must solve it.

A good mission brief tells the agents what result is required while leaving room for them to decide how to achieve it. Too little information creates guessing. Too much instruction turns planning into compliance with a script.

The Mission Brief provides a compact set of fields for objective, intelligence, authorities, constraints, support, timing, consequences, and exit conditions. Fill only what the sponsoring organization knows at the start. Unknowns stay unknown, assumptions stay visible, and the players get a document they can plan against.

“Find out what’s happening” sounds like an assignment, but it gives the team no way to know when the work is complete. Intelligence requirements convert a broad concern into specific questions that can be researched, observed, tested, compared, and reported.

Use this brief before an investigation, surveillance operation, research task, or mission-planning session. Start with one decision the intelligence must support, choose the questions that matter, then record what would count as enough information. The mission becomes easier to run because every lead can be judged against a known requirement.

About 20 million barrels of oil per day and roughly one-fifth of global LNG trade passed through the Strait of Hormuz in 2024. That traffic moves through a narrow commercial corridor governed by navigation rules, maritime institutions, port procedures, shipboard systems, and overlapping legal jurisdictions.

OSINT-6: Strait of Hormuz Fact Sheet turns that civilian maritime environment into a usable roleplaying reference. It covers the geography and commercial role of the strait, Iran and Oman as the littoral states, Persian Gulf access, international shipping rules, merchant-vessel operations, civilian maritime security, and the public records that can be used to identify and research commercial ships. The book takes no position on current conflicts, assigns no motives or blame, and provides no mission seeds or fictional adversaries.

This 48-page Fact Sheet includes:

• A concise reference to the Strait of Hormuz, its geography, traffic organization, and commercial importance

• Civilian maritime institutions in Iran and Oman

• UNCLOS, transit passage, traffic separation, COLREG, and jurisdiction explained for play

• Merchant-shipping systems including AIS, LRIT, GMDSS, ECDIS, VDR, and IMO ship identification numbers

• Civilian maritime security and OSINT-6 equipment mappings

• The new Commercial Ships Qualification

• Nine OSINT-6 commercial vessel profiles, from VLCCs and LNG carriers to harbor tugs and pilot boats

• Rules for dense commercial traffic, moving-platform observation, vessel transfers, exposure, and poor visibility

• Maritime intelligence procedures for vessel identification, ownership research, port calls, cargo research, communications, and regulatory records

• A Maritime Intelligence Record, quick-reference material, glossary, and index

Use it as background for a contemporary operation, a historical campaign, or any OSINT-6 scenario involving commercial shipping and the Persian Gulf. The Fact Sheet supplies the verified reference material and game procedures. What happens there is left to your table.

A case officer can recruit the source. Someone still has to define the requirement, assess the reporting, maintain the technical systems, protect the team, and tell headquarters what happened.

OSINT-6: CIA Fact Sheet brings the real, publicly documented Central Intelligence Agency to the game table. It covers the agency’s mandate, legal limits, oversight, organization, careers, facilities, and public priorities, then converts that material into practical OSINT-6 character and equipment choices.

This 36-page sourcebook includes ten occupational packages, from Case Officer and Analyst to Technical Intelligence Officer, Protective Officer, and Paramilitary Operations Officer. Each package provides class, Profession, skill, qualification, Origin feat, advancement, and assignment recommendations. The CIA agent procedure records office, clearance, cover, authority, equipment, and reporting chain, while the mission-team section shows how specific intelligence requirements determine lead and supporting roles.

Eight assignment packages connect agency work to existing OSINT-6 equipment profiles. Seven historical artifacts from the CIA Museum receive game treatments, including the TAR-224 radio, Minox B camera, concealed Tessina camera, and escape and evasion survival kit. Two reference tables, a complete index, and 81 footnotes support play and further research.

Build a CIA agent, assemble a mission team, or place the agency within an existing campaign. Every package connects documented intelligence work to OSINT-6 rules without granting undefined access or unlimited authority. Requires the OSINT-6 Core Rulebook.

Military and police sidearms documented for reference, identification, and OSINT-6 play.

A service pistol can identify an organization, a procurement program, a national standard, or a period of issue. Model, cartridge, and capacity can turn a routine sidearm into useful evidence or a meaningful equipment choice.

The Service Pistol Fact Sheet profiles real military and police handguns in a consistent format. Each entry records origin, service period, known users, cartridge, capacity, and OSINT-6 statistics for damage, range, loudness, access, qualification, size, and traits.

Use the profiles to equip agents, officers, soldiers, guards, contacts, and adversaries with specific sidearms. The same entries support weapons identification, procurement research, recovered evidence, and missions where the model in a holster provides valuable context.

Replace generic duty handguns with researched, recognizable weapons using the Service Pistol Fact Sheet.

A mission in the United States can cross federal authorities, state and local jurisdictions, private infrastructure, military installations, diplomatic channels, and public scrutiny before the agents ever reach their target.

The OSINT-6 United States Factbook turns that complexity into a grounded modern espionage setting. Current research establishes the country’s geography, population, government, economy, infrastructure, security institutions, and international relationships. Seven locations receive additional operational coverage, from Washington and New York City to the Port of Los Angeles, the San Diego-Tijuana border region, and Alaska’s North Slope.

At the center of the book stands the Administrative Coordination Office, a fictional American intelligence organization built for deniable interagency missions. The Office can employ the agents, support them, compete with them, conceal its failures, or become the threat they must confront. Its history, authority, oversight, personnel, divisions, facilities, doctrine, capabilities, internal conflicts, and current priorities provide a complete institutional framework for play.

Inside, you’ll find:

• Six complete agents, one at each level from 1 through 6, ready for use as player characters, allies, rivals, superiors, or antagonists

• New Technical and Social Feats, compartment authorization, interagency mission credentials, and sponsored cover support

• Thirty real-world equipment entries mapped to OSINT-6 Core Rulebook profiles, including firearms, communications systems, surveillance equipment, tactical gear, vehicles, and aircraft

• Six new operational procedures covering protected retrieval, domestic collection authority, border device inspection, interagency communications, federal record exposure, and divided authority

• Operation Dead Letter, a complete mission involving a missing communications engineer, a dormant relay network, conflicting federal interests, and a retrieval order that may conceal more than it reveals

• Six additional Mission Briefings for individual sessions or continuing campaigns

• Reference summaries, cross-references, Information Records, authority forms, mission documents, a vehicle record, an area map, and other player handouts

Every chapter separates documented reality from fictional game material. The result gives the Game Master a researched operational environment while preserving the freedom to decide who controls the Office, what its missions protect, and how far its personnel will go.

Bring OSINT-6 operations onto American ground, where access leaves records, authority has limits, and every agency enters the mission with its own objective.

Requires the OSINT-6 Core Rulebook.
