ARM = Anti-radiation missile.
From the Internet web site southfront.org 07.08.2022 [August 7 2022].
YES indeed, we can agree this is a surprise!
"The US has reportedly supplied Kiev Forces with advanced anti-radiation missiles in a bid to weaken air defenses providing cover to the ongoing Russian special military operation in Ukraine."
"On August 7, Russian sources shared photos showing the remains of a US-made AGM-88 HARM anti-radiation missile, that was allegedly launched by Kiev forces, near a position of the Russian military in an unspecified part of Ukraine."
Anti-radiation as better defined and understood as anti-radar missile. Used in the SEAD role. Suppression Enemy Air Defense [SEAD].
The AGM-88 can be launched from several advanced Western fighter jets, none of which are in service with the Ukrainian Air Force. It is possible that Kiev forces have been firing AGM-88 missiles from ground-based launchers.
Air-to-ground anti-radar missile being launched from the ground!
