Military Terms

Asymmetric Warfare

Combat strategy employed by a weaker force against a stronger adversary, using unconventional methods such as guerrilla tactics, IEDs, cyber attacks, and proxy forces to offset conventional military disadvantages. Iran's primary strategic doctrine against US/coalition forces.

BDA (Battle Damage Assessment)

Post-strike evaluation of the effectiveness of military operations, including physical damage to targets, functional impact on enemy capabilities, and collateral effects. Critical for determining whether follow-up strikes are required.

C2 (Command and Control)

The exercise of authority and direction by a military commander over assigned forces. Disruption of C2 nodes was a primary objective of the opening US-Israeli strikes against Iran, targeting communications infrastructure and headquarters facilities.

Carrier Strike Group (CSG)

A naval formation centered on an aircraft carrier, typically including guided-missile cruisers, destroyers, and support vessels. The USS Abraham Lincoln CSG was deployed to the Middle East as part of the pre-conflict buildup.

Decapitation Strike

Military operation specifically targeting enemy leadership to eliminate command authority and create organizational paralysis. The Feb 28 strikes that killed Supreme Leader Khamenei and 40+ senior commanders represent a textbook decapitation operation.

Deterrence

Strategy of preventing adversary action through the credible threat of unacceptable retaliation. Iran's missile arsenal and proxy network served as its primary deterrent, which ultimately failed to prevent the US-Israeli campaign.

EW (Electronic Warfare)

Military operations involving the use of electromagnetic energy to control the electromagnetic spectrum, including jamming enemy communications, disrupting radar systems, and protecting friendly electronic systems from interference.

ISR (Intelligence, Surveillance, and Reconnaissance)

Coordinated acquisition, processing, and dissemination of timely intelligence to support military operations. Includes satellite imagery, signals intelligence, drone surveillance, and human intelligence networks.

Operation Epic Fury

US military codename for the campaign against Iran, launched February 28, 2026. Encompasses air and naval strike operations, cyber warfare, and force protection across the theater.

Operation Roaring Lion

Israeli military codename for coordinated operations against Iran, conducted simultaneously with US Operation Epic Fury. Focused on strategic targets in Tehran, Isfahan, and other Iranian military-industrial centers.

Proxy Force

Non-state armed group operating on behalf of a state sponsor, providing deniable force projection without direct military engagement. Iran's proxy network includes Hezbollah (Lebanon), Houthis (Yemen), and various Iraqi and Syrian militias.

SEAD (Suppression of Enemy Air Defenses)

Military operations to neutralize, destroy, or degrade an adversary's air defense systems, enabling follow-on air operations. A critical first-phase objective in the US-Israeli strike campaign against Iran.

THAAD (Terminal High Altitude Area Defense)

US-built missile defense system designed to intercept short-, medium-, and intermediate-range ballistic missiles during their terminal phase. Deployed to protect coalition assets and regional allies from Iranian missile retaliation.

Iranian Political and Organizational Terms

Assembly of Experts

Elected Iranian body of 88 senior clerics responsible for selecting, monitoring, and, in theory, removing the Supreme Leader. Following Khamenei's death, the Assembly faces the unprecedented task of selecting a successor during wartime.

Artesh

Iran's conventional military (Army, Navy, Air Force), distinct from the IRGC. While numerically large, the Artesh receives less funding and political influence than the Revolutionary Guards and is generally regarded as less capable.

Basij

Volunteer paramilitary organization operating under IRGC command. Used domestically for internal security and protest suppression, and potentially mobilizable for homeland defense during wartime. Estimated strength of several million volunteers.

IRGC (Islamic Revolutionary Guard Corps)

Iran's elite military and political force, operating parallel to the conventional Artesh military. Controls Iran's ballistic missile program, proxy network, naval asymmetric forces, and significant economic interests. Estimated 190,000+ active personnel.

Quds Force

The IRGC's extraterritorial operations division responsible for intelligence gathering and unconventional warfare outside Iran's borders. Manages relationships with proxy forces across the Middle East including Hezbollah, Hamas, and Iraqi militias.

Supreme Leader

Iran's highest political and religious authority, serving as head of state, commander-in-chief, and ultimate arbiter of domestic and foreign policy. The position was held by Ayatollah Ali Khamenei from 1989 until his death on February 28, 2026.

Geopolitical and Diplomatic Terms

APT (Advanced Persistent Threat)

State-sponsored or state-affiliated hacking groups that conduct prolonged, targeted cyber intrusions against high-value networks. Iranian APT groups (e.g., APT33, APT34, APT35) are assessed to have capabilities against critical infrastructure.

CAATSA (Countering America's Adversaries Through Sanctions Act)

US legislation imposing mandatory sanctions on Iran, Russia, and North Korea. Provides the legal framework for extensive economic penalties on entities conducting business with sanctioned Iranian sectors.

Escalation Ladder

Analytical framework for understanding progressive conflict intensification, from diplomatic tensions through conventional military operations to potential nuclear exchange. Used to assess current conflict position and forecast trajectories.

Five Eyes

Intelligence-sharing alliance comprising the United States, United Kingdom, Canada, Australia, and New Zealand. Provides the foundational signals intelligence and surveillance architecture supporting coalition military operations.

IAEA (International Atomic Energy Agency)

United Nations body responsible for monitoring nuclear programs and enforcing non-proliferation agreements. The IAEA confirmed that no Iranian nuclear installations were struck in the initial US-Israeli campaign.

JCPOA (Joint Comprehensive Plan of Action)

The 2015 Iran nuclear deal between Iran and the P5+1 (US, UK, France, Russia, China, Germany), which limited Iran's nuclear enrichment in exchange for sanctions relief. The US withdrew in 2018 under Trump's first term; the agreement was effectively defunct before the current conflict.

War Powers Resolution

US federal law (1973) requiring the President to notify Congress within 48 hours of committing armed forces to military action and prohibiting forces from remaining beyond 60 days without Congressional authorization. Trump submitted notification on February 28.

Economic and Energy Terms

Brent Crude

The global benchmark for oil pricing, based on crude extracted from the North Sea. Brent surged 13% following the onset of hostilities, reflecting market concern over Strait of Hormuz disruption and Middle Eastern supply risk.

LNG (Liquefied Natural Gas)

Natural gas cooled to liquid form for transport by tanker. Qatar, the world's largest LNG exporter, ships through the Strait of Hormuz, making LNG markets particularly vulnerable to the current conflict.

SCADA (Supervisory Control and Data Acquisition)

Industrial control systems used to monitor and manage infrastructure such as power grids, water treatment, and oil/gas facilities. SCADA systems are a primary target category for Iranian cyber operations against adversary critical infrastructure.

SPR (Strategic Petroleum Reserve)

Emergency stockpile of crude oil maintained by the US government (currently ~400 million barrels). Release of SPR oil is one tool available to mitigate price spikes caused by supply disruptions like the Hormuz closure.

Strait of Hormuz

Narrow waterway (approximately 33 km wide at its narrowest point) connecting the Persian Gulf to the Gulf of Oman and open ocean. Approximately 20% of the world's daily oil consumption transits through the strait, making it the most critical energy chokepoint globally.

WTI (West Texas Intermediate)

The primary US oil price benchmark, representing light sweet crude oil. WTI rose to approximately $75.40/barrel following the conflict's onset, though the Brent-WTI spread widened as Middle Eastern supply risk is more directly reflected in Brent pricing.

Intelligence and Cyber Terms

COMINT (Communications Intelligence)

Intelligence derived from intercepting enemy communications, including radio transmissions, telephone calls, and digital messaging. A key capability of Five Eyes alliance supporting targeting and situational awareness.

DDoS (Distributed Denial of Service)

Cyber attack that overwhelms a target's servers or network infrastructure with traffic, rendering services unavailable. A relatively unsophisticated but disruptive tool in Iran's cyber arsenal.

HUMINT (Human Intelligence)

Intelligence gathered through human sources, including agents, informants, and diplomatic contacts. Particularly valuable for understanding leadership intentions and internal political dynamics that technical collection cannot reveal.

SIGINT (Signals Intelligence)

Intelligence collected by intercepting electronic signals and communications. The primary collection discipline of the NSA and Five Eyes partners, critical for monitoring Iranian military communications and missile telemetry.

Analytical Terms

Black Swan Event

A highly improbable occurrence with three characteristics: unpredictability, massive impact, and post-hoc rationalization. In the context of this conflict, examples include nuclear weapon detonation, state collapse, or great-power military intervention.

Confidence Level

An analytical metric indicating the degree of certainty in an assessment. High (>75% certainty): based on multiple corroborating sources. Medium (40–75%): reasonable inference with some information gaps. Low (<40%): speculative with significant uncertainty.

Fog of War

The inherent uncertainty, confusion, and incomplete information that characterizes active military operations. A primary reason why early conflict reporting is frequently revised as more complete information becomes available.

Red Team / Blue Team

Analytical methodology where one group (Red Team) simulates adversary decision-making while another (Blue Team) represents friendly forces. Used to stress-test assumptions and identify vulnerabilities in strategic planning.
