To accomplish the missions here requires going through time warp machines that appear on all stages. But when you're on a stage where one of your fellow time soldiers who need to be rescued is located, you should avoid entering the time warp machines, otherwise, it'll take longer to complete the missions, as you'll need to access more time machines on other stages until you get back to the specific stage where you need to find the captive. For example, if one of the captive soldiers is located on the Age of Rome stage, remain on that stage until you've reached and defeated the main boss enemy. The captive soldier will then materialize and the game will tell you that 'you destroyed the boss monster and rescued one warrior'. Then, you'll proceed to the next mission to rescue another captive soldier.
