In the documentation, the definition is actually that it is not necessarily a delivery, but instead as a "different form of involvement". This seems misleading with regard to the table heading.
companies involved in arms exports to war zones and warring states
"global overview of companies that are involved in arms exports to war zones and warring states. It currently covers almost 600 companies, including parent companies, subsidiaries and joint ventures. It is not a general look at defence companies, but specifically at companies that are involved in various ways in arms deliveries to war zones."
"The starting point for the database is the selection of conflict actors/conflict states based on the Heidelberg Conflict Barometer. It has been published by the renowned Heidelberg Institute for Conflict Research since 1992. Compared to its peers in empirical conflict research, this institute integrates qualitative criteria more strongly in its research in order to categorize states as crisis or war zones. This makes it possible to identify conflict dynamics at an early stage.
Only conflicts that reached conflict intensity 4 (limited war) or 5 (war) at least once in the period from 2016 to 2021 were included in the current version of ExitArms.org. Intensity levels one and two include non-violent conflicts. Level three describes conflicts in which violence is used without the use of military weapons. The conflict intensity definition by the Heidelberg Conflict Barometer is based on an assessment of the conflict consequences in terms of victims, refugees, militarization, degree of organization of violence, and destruction of infrastructure. Additionally: ExitArms.org does not include conflicts for which the United Nations Security Council has issued a mandate under Chapter VII of the United Nations Charter that includes the use of force."
