The Ukrainian Defense Ministry has launched an internal inquiry into possible irregularities in the purchase and quality of TOR helmets made by UA.RPA.

"During the preliminary testing of TOR helmets questions arose about the product's quality. For the purpose of a full and objective investigation, samples were sent to the Interior Ministry's forensic science center and helmet deliveries to the national armed forces have been suspended for the duration of inquiry," the ministry said on its website on Friday.
