Public web sources are sparse outside the company's own site, so this profile keeps most product claims limited to official InterProInvest pages, Defense Express reporting, Ukrainian Military Pages reporting, and a reusable Wikimedia Commons image. Public references alternate between InterProInvest, Interproinvest, and IPI; the catalog facet normalizes those spellings to InterProInvest.
