Operational Planning Reference

Briefing Structure (SMEAC)
Situation	What Delta Green knows. What the threat is. What has been observed or reported. Keep brief — agents do not need the full picture.
Mission	The single tasking statement. Who does what, where, when, and why. Should fit in one sentence.
Execution	How the mission is to be carried out. Phase lines, entry/exit routes, contingencies for compromised cover or armed contact.
Admin & Logistics	Green Box location and contents. Cover identities in use. Vehicles, safe houses, local resources. Medical evacuation plan.
Command & Comms	Who is cell leader. Emergency contact procedure. Duress code. Exfil signal if comms go dark.

Threat Assessment Levels
Level 1 — Mundane	No confirmed unnatural activity. Human actors only. Standard law enforcement precautions apply.
Level 2 — Suspicious	Unnatural indicators present but unconfirmed. Possible cult or artifact involvement. Approach with caution; maintain cover.
Level 3 — Confirmed Unnatural	Active unnatural entity or ritual confirmed. Standard firearms likely insufficient. SAN risk is high. Do not engage alone.
Level 4 — Critical	Potential mass-casualty or reality-threatening event. Containment priority. Agents may be considered expendable. Escalate immediately.
Level 5 — Extinction-Class	Entity or ritual capable of catastrophic harm. Nuclear or other extreme options authorised by Program leadership only. All cells on alert.

Agent Resources
Federal Credentials	FBI, CDC, FEMA, or DoD cover IDs. Opens doors with local law enforcement and government agencies. Use sparingly — can be traced.
Safe Houses	Pre-arranged locations known only to the cell. Stocked with 72-hour emergency supplies, basic medical kit, and one burner phone.
Delta Green Favors	Call on Program contacts for forensic analysis, legal extraction, records access, or specialist knowledge. Each favor costs operational goodwill.
Emergency Funds	Cash reserves for equipment, bribery, or rapid exfiltration. No receipts. No paper trail. Amount determined by Handler.
Specialist Support	Temporary attachment of assets: field medic, signals intelligence, demolitions expert. Arranged through Case Officer with 24–48 hours notice.

Cell Structure
Agents	Frontline operatives. Need-to-know only. Do not know the identity of other cells.
Cell Leader	Coordinates 2-5 agents. Receives orders from Case Officer. Takes point on field decisions.
Case Officer	Handles tasking and debriefs. Insulated from direct field exposure. Reports upward only.

Green Box / Opera Box Handling
What is a Green Box	A pre-positioned cache of supplies and equipment. Usually a storage unit, rented garage, or locker rented under a false name, paid in cash.
What is an Opera Box	A classified intelligence package — documents, recordings, or artifacts — held separately from field equipment. Higher access controls than a Green Box.
Weapons & Ammo	Unregistered firearms, spare magazines, cleaning kit
Comms	Burner phones (sealed), encrypted radios, one-time pad
Documents	Cover IDs, cash (mixed denominations), false plates
Medical	Trauma kit, painkillers, antibiotics, tourniquet
Intel	Target photos, area maps, emergency contact numbers
Access Protocol	Only the assigned cell accesses the box. Location shared on a need-to-know basis. If the box is burned, report immediately and do not return.
Sanitisation	After a operation, remove or destroy anything that could link back to the Program. Wipe prints. Replace unused items. Do not leave biological material.

Cover Identity Management
Legend	Backstory must be verifiable — employer, address, social media presence
Documentation	Driver's license, credit card, matching receipts in wallet
Behaviour	Stay in legend. Do not contact real-world associates. Limit anomalies.
Burn protocol	If cover is blown: abort, sanitise site, go to emergency RV point
Depth of Cover	Shallow cover (24–72 hours): minimal backstory, single ID. Deep cover (weeks+): full legend, employment history, social ties, online footprint.

Communication Protocols
Dead Drops	Pre-arranged physical locations. Chalk mark signals deposit. Never meet in person.
One-Time Pads	Unbreakable if used correctly. Each page destroyed after use. Never reuse.
Burner Phones	Purchased with cash. Calls kept under 90 seconds. Discarded after first use if compromised.
Recognition Signals	Verbal challenge/response pairs. Rotate every operation cycle.

Unnatural Entities

Entity	SAN Loss	HP	Notable Abilities
Deep One	0/1d6	12	Amphibious, superhuman strength
Mi-go	1/1d10	14	Flight, advanced technology
Shoggoth	1d6/1d20	50	Shapeshifting, immense strength
Byakhee	1/1d8	16	Interstellar flight, resilient
Ghoul	0/1d6	10	Burrowing, pack hunters
