The United States Army has joined in the chorus of praise and tributes honoring its former servicemember -- the late, great Stan Lee."Rest in peace, Soldier," the organization tweeted. "Comic book creator @TheRealStanLee has passed away at the age of 95. Lee served in the #USArmy Signal Corps during WWII from 1942-1945. We are deeply grateful for his service to our country and for his tremendous support to servicemembers. #Excelsior!"

Just after writing Captain America at Timely Comics, Lee entered the U.S. Army in early 1942, serving as a member of the Signal Corps and repairing communications equipment. Thanks to his artistic side, he would later be transferred to the Training Film Division, where he wrote manuals, training films, slogans and cartoons under the military classification of "playwright."

When Lee returned from his World War II military service in 1945, he'd resume his comic duties at Atlas Comics (a rebranding of Timely Comics, which would later go on to become Marvel). For his dedicated service, Lee was inducted into the Signal Corps Regimental Association, receiving honorary membership of the 2nd Battalion of 3rd U.S. Infantry Regiment out of Joint Base Lewis-McChord at the 2017 Emerald City Comic Con.

It's a bittersweet post, especially as Lee's last official tweet paid homage to Veterans Day, with the legend sharing an image of himself on army duty.
