This is the best summary I could come up with:
They were trained in amphibious landings - using inflatable boats to conduct beach raids - and will now head to the frontline.
The commandos were trained the use of Next Generation Light Anti-Tank Weapons (NLAW) and Stinger anti-aircraft missiles - as well as the use of mortars and drones for reconnaissance, and explosive demolition of obstacles such as Dragon's Teeth anti-vehicle fortifications.
Although some of the Ukrainian trainees already had experience in the armed forces or on the frontline, many are civilian volunteers with no military background.
One of the recently trained Ukrainian marines said the course from the Royal Marines was "far more intense that I expected", and added: "All the way through, our British instructors have been beside us, showing us how to move and how to work together in a small team - this will make a difference when we return home to Ukraine."
Defence Secretary Ben Wallace said: "The UK has led the way in training the Armed Force of Ukraine, providing world-leading training in frontline combat skills to more than 20,000 of Ukraine's Army recruits through Operation Interflex.
"This programme of training, delivered by elite British commandos, will support Ukraine to build its own distinct marine force and expand its capability to operate in a maritime environment."
