Uses of Force
Blockade Use of ships, planes or troops by one state to seal off the territory of another state so as to prevent entry or exit of goods or personnel. Boarding, stopping, or inspection of ships, land vehicles or the confiscation of goods is sufficient evidence for the erection of a blockade.	Armed force blockade	IDEA event forms are not bound to actors so references to military actors in MID need to be filtered in a post coding procedure.
Clash Outbreak of military hostilities between regular armed forces of two or more system members, in which the initiator may or may not be clearly identified.	Armed battle	IDEA event forms are not bound to actors so references to military actors in MID need to be filtered in a post coding procedure.
Declaration of war Official statement by one state that it is in a state of war with another state.	Declare war	IDEA event forms are not bound to actors so references to military actors in MID need to be filtered in a post coding procedure.
Occupation of Territory Use of military force by one state to occupy the whole or part of another state's territory for a period of more than twenty-four hours. The immediate occupation after a war by the victorious side's army is not coded as an incident unless provisions of the treaty are violated by the occupying forces or further militarized incidents are undertaken by the state being occupied.	Armed force occupation	IDEA event forms are not bound to actors so references to military actors in MID need to be filtered in a post coding procedure.
Raid Use of regular armed forces of a state to fire upon the armed forces, population, or territory of another state. Within this incident type, the initiator can be clearly identified and its action is not sanctioned by the target.	Armed actions	IDEA event forms are not bound to actors so references to military actors in MID need to be filtered in a post coding procedure.
Seizure Capture of material or personnel of official forces from another state, or the detention of private citizens operating within contested territory. Seizures must last at least twenty-four hours to be included.	Seize	IDEA event forms are not bound to actors so references to military actors in MID need to be filtered in a post coding procedure. IDEA does not distingusih between seizures of less than a day and more than a day. Because MID includes both seizure of people (IDEA codes 212 & 213) and things (IDEA code 211), the highest level of aggregation (to the IDEA cue code 21) must be used in IDEA to match this MID event form.
Use of CBR weapons Use of chemical, biological or nuclear weapons from the arsenal of one state employed against the territory or forces of another resulting in less than 1,000 total battle deaths per dispute.	Unconventional weapons attack	IDEA event forms are not bound to actors so references to military actors in MID need to be filtered in a post coding procedure.
