It's a graphic display of how people in the north of Yemen see America's role in a war that's been tearing into the fabric of their country for exactly four years.
The US is Saudi Arabia's biggest arms supplier. The jets and the bombs they drop as well as the tanks, artillery pieces and vehicles used by Saudi Arabia and the United Arab Emirates, who lead a coalition against Yemen's Iran-backed Houthi movement, are mostly US-made.
Without them, the coalition forces on the outskirts of Hodeidah would not have been able to threaten the port city, the Houthis believe.
