"Deflecting" 18 older model Russian SA-16 Gimlets, which have been being phased out for a decade.

Take it or leave it, but Ukraine is claiming[0] they shot down two Ka-52 helicopters in the past week and there is photographic evidence[1] of one being heavily damaged (although still flyable) yesterday.

Also estimates[2] are that 25% of Russian's total fleet of Ka-52 helicopters have been shot down during the Ukraine war. "Russian attack helicopters have likely suffered particular attrition from Ukrainian man-portable air defense systems"

So maybe impressive but not an invulnerability shield.
