Before the turnover ceremony, Duterte boarded the anti-submarine ship Admiral Pantaleev docked at Pier 15 at the Port of Manila.
In the acceptance certificate signed by Russian Federation and the Philippines, around 20 military vehicles, 5,000 Kalashnikov assault rifles, a million rounds of ammunition, and 5,000 steel helmets were granted to the Philippine troops.
This is despite President Rodrigo Duterte's pronouncement that American forces should leave Mindanao.
Defense Secreatary Delfin Lorenzana and Russian Defense Minister Sergei Shoigu were also at the Port of Manila to witness the transfer of equipment.
"It was a tough fight", Mattis said during his flight, adding he thought the Philippines had sent "a very necessary message to the terrorists".
The turnover happened a day after the Philippines and Russian Federation signed an agreement on military and technical cooperation.

U.S. Ambassador Sung Kim played down any U.S. concerns about Duterte's outreach to China and Russian Federation and noted that the United States, a former colonial power, was the country's only treaty ally, with far deeper ties in the Philippines.
CLARK, Philippines-The timing of U.S. Defense Secretary Jim Mattis' trip to the Philippines this week couldn't have been better, coming just as it celebrated a victory against Islamist militants in Marawi city-with a critical dose of help from the U.S. military. More than 100 people were killed in hostilities.
The commander in chief issued Proclamation 216 declaring Martial Law and suspending the privilege of the writ of habeas corpus in the whole of Mindanao including the islands of Basilan, Sulu, and Tawi-Tawi last May 23 following the terror attack of the ISIS-affiliated Maute Group in Marawi City.
China has also donated thousands of assault and sniper rifles to the Philippines in a similar gesture of friendship.
