The National Guard deployed an immediate reaction force to the US Capitol on Friday afternoon after someone rammed a car into a police checkpoint.

The IRF consisted of soldiers and airmen ready to support the Capitol Police, the Guard said in a statement, adding that "due to operational security, we cannot discuss further details regarding the IRF."

Guard troops were lined up around the perimeter of the Capitol and were wearing face shields and carrying riot shields. Some appeared to have sidearms; however, most wielded batons in addition to the shields.

The Capitol Police said on Friday afternoon that the person had "rammed a vehicle into two USCP officers."

The National Guard presence is significantly smaller than the more than 25,000 members who were deployed following the riot at the Capitol complex on January 6 and amid the heightened security around President Joe Biden's inauguration.

There have been allegations that the Pentagon dragged its feet with the National Guard response to the riot, delaying a necessary call to action by three hours.

While the Guard presence has diminished since January, it remains elevated because of persistent security concerns.
