“They gave their tomorrows for our todays” is a military saying (popular on Memorial Day) that has been printed on many images.
   
“When you go home, tell them of us and say, ‘For your tomorrow, we gave our today‘“ (from 1918 and 1944) is the original saying. “They gave their tomorrow for our today” is a similar saying.
 
“They died for the rights of Americans to enjoy their freedoms. They gave their tomorrows for our todays” was printed in the News Messenger (Marshall, TX) on May 31, 1994. The saying has been popular on Twitter.

They shall grow not old….as we that are left grow old
Age shall not weary them, nor the years contemn*
At the going down of the sun, and in the morning, we will remember them
