Joe Biden delivered the commencement speech at West Point military academy in New York, on Saturday, 25 May.
The US president's address to around 1,000 US Army cadets comes as part of a push by Mr Biden to highlight his administration's efforts to support active and retired military personnel.
Efforts include a bipartisan law Mr Biden signed two years ago to help veterans who have been exposed to burn pits or other poisons have easier access to healthcare.
In his speech he highlighted the heroism of Allied forces in the Second World War and threats to democracy today.
As vice president, Mr Biden twice addressed a graduating class of cadets at the academy but this will be the first time he does so as president.
Today's speech comes after the Democratic president gave the commencement speech at Morehouse College.
