“The U.S. has pledged 113 Bradleys, so at most 15% is 17 Bradleys.”
Source article says 16 of 111.
I was basing my numbers on this April 2023 War Zone article:

Dietz would not say when they arrived or how many have arrived, deferring those questions to the Ukrainian Defense Ministry (MoD). The U.S. has promised 113 Bradleys to Ukraine, including 109 M2A2-ODS-SA variants and four BFIST versions.
