The U.S.military's casualty figures from the conflict with Iran have increased significantly, with over 18 troops killed and 624 wounded since February 28.

The Pentagon updated its Defense Casualty Analysis System (DCAS) database on July 7, introducing a new 'Overseas Operations' category to track casualties.This change led to a surge in reported injuries, surpassing the previous peak of 482.However, media and lawmakers raised concerns after initial data discrepancies caused fluctuating casualty numbers.The Pentagon attributed the changes to temporary technical issues on the DCAS website, though details remain unclear.The new category includes specific incidents like the deaths of three Army soldiers in Jordan and a soldier in Iraq from Iranian strikes.

The timing of these updates coincides with President Trump's assertion that a new conflict with Iran began on July 7, which has sparked debate over the interpretation of the War Powers Act.

Lawmakers from both parties have criticized the administration's approach to extending military operations without congressional approval, highlighting ongoing tensions between executive authority and legislative oversight.
