AceShowbiz - Chris Pratt has paid an emotional tribute to fallen veterans. Celebrating Memorial Day, the actor famous for his portrayal of Star-Lord in the "Guardians of the Galaxy" film series urged fellow Americans through a new social media post to "show support for our fallen."

On Sunday, May 30, the 41-year-old shared his heartfelt message via Instagram. "We run the risk of losing that decency when we fail to instill gratitude in the minds of our youth or the perspective of what it actually means to be free - should they never learn of the selfless sacrifice of our armed service members in the face of oppressive evil," he noted. "So join me in showing support for our fallen."

In accompaniment of heartbreaking photos displaying grieving family members and soldiers, Chris penned, "I saw these images on @timkennedymma feed. Please, look at each one. Pause, give them your consideration." He continued, "From the Union Army defeating slave owning confederates, to the Greatest Generation and her Allies vanquishing the Nazis or our special operators hunting down the perpetrators of 9/11."

"We count the names of each fallen soldier lest they be countless. They are the good guys. They know pain and suffering we never will," the actor who plays a veteran in his upcoming film "The Tomorrow War" continued reminding others. He added, "They have given us the most free and decent society planet earth has ever seen."

Chris went on to advise others to "take a quiet moment to really consider the sacrifice." The "Jurassic World" actor further wrote, "And if you use the comments section on posts like this to b**ch and moan about America please understand there are countries in the world where criticizing your government will get you killed or imprisoned."

"Criticism is a right and necessity in amending the flawed systems of man. So by all means, let your voice be heard. But never forget your right to free expression is paid for in blood," the husband of Katherine Schwarzenegger insisted. He concluded his lengthy post by stating, "May God give their souls rest, and may they live in our memories this weekend and always."
