Even as the U.S. military takes on a greater role in the warfare in Iraq and Syria, the Trump administration has stopped disclosing significant information about the size and nature of the U.S. commitment, including the number of U.S. troops deployed in either country.
Earlier this month, the Pentagon quietly dispatched 400 Marines to northern Syria to operate artillery in support of Syrian militias that are cooperating in the fight against Islamic State, according to U.S. officials. That was the first use of U.S. Marines in that country since its long civil war began.
In Iraq, nearly 300 Army paratroopers were deployed recently to help the Iraqi military in their six-month assault on the city of Mosul, according to U.S. officials.
Neither of those deployments was announced once they had been made, a departure from the practice of the Obama administration, which announced nearly all conventional force deployments.
