Military column in Porto due to housing protests?

A video circulating on social media suggests military vehicles were deployed due to a housing protest in Porto. However, the vehicles were being transported on trailers and there is no evidence of military intervention in the protests. According to Portuguese law, the Armed Forces are not considered internal security forces and cannot intervene in public order without a state of emergency. The military vehicles' presence coincided with Army Day celebrations, which included public events in Porto. Therefore, the claim linking the military column to the protest is incorrect.
