(QHA) -

The United States has delivered more than 100 pieces of military equipment to vulnerable NATO-allied Baltic states.

The deliveries are intended to “demonstrate resolve to President Putin and Russia that collectively we can come together,” U.S. Maj. Gen. John R. O’Connor told AFP as he oversaw the delivery of the equipment in the port of Riga.

The delivery included Abrams tanks, Bradley fighting vehicles, Scout Humvees and support equipment and O’Connor said they would stay “as long as required to deter Russian aggression.”

The three former Soviet-ruled Baltic states of Estonia, Latvia and Lithuania, all NATO and European Union members since 2004, have very little military hardware of their own.

Crimea’s last year unification with Russia and Russia’s role in Ukrainian conflict have galvanized NATO and focused particular attention on its vulnerable Baltic members.
