The first cohort of Ukrainian troops come to the end of their training in the UK this week, the Defence Secretary has told MPs.
Ben Wallace also told the Commons that it has been a "learning experience for both sides".
The programme is part of the UK's support for the country in its fight against Russia's unprovoked invasion.
Mr Wallace also said the UK will "continue to invest and improve on that course" and announced that "the Dutch have declared that they are going to send people to support in the training".
He said: "It is quite an amazing thing to see men from 18 to 50, and there'll be some women soon as part of the deployment, sometimes getting off planes in tracksuits being trained in the basics of the battlefield, skills, law of armed conflicts etc."
Mr Wallace did however highlight the "sobering" fact some of the Ukrainian recruits taking part in the UK military training programme will soon return to a warzone where many of them "tragically will pay the ultimate sacrifice".
Watch: Ben Wallace visited Ukrainian troops training in the UK earlier in the month.
The Ukrainian recruits are part of the Government's commitment to training 10,000 troops every 120 days.
About 600 have been taking part in a programme in northwest England being run by 11th Security Force Assistance Brigade.
Deployed to run the programme are 1,000 UK service personnel, with the training taking place at Ministry of Defence sites across the UK.
