About Capt. Allen[]
When Hawkeye, on a whim, reminiscing about the wounded soldiers who had passed through the 4077th, and others, such as Colonel Blake and Trapper John, decides to build a memorial to all of the people who have passed through the 4077th after the camp gets an erroneous surplus of tongue depressors he ordered (the 4077th received 500,000 instead of 5,000!), Klinger, under the thrall of his new scheme of running a 4077th newspaper, tells Stars & Stripes about Hawkeye's tower. Capt. Allen, on behalf of the newspaper, arrives with a photographer, and he tells Hawkeye his sculpture should be taken on tour, thinking it will be "great for recruitment."
Hawkeye is horrified - recruitment? Turns out that Allen is from the Army, not Stars & Stripes, and he's looking at Hawkeye's tower as a propaganda tool. He asks to take a picture of it with Hawkeye alongside, but he stalls them and asks them to come back in a few minutes.
Later in the afternoon, Hawkeye tells them the tower's ready. We see that the tower now has an explosive called Primacord (taken from a patient who was sent home) wrapped around it, and he has Klinger blow it up just as the picture is snapped!
Capt. Allen is completely flabbergasted, asking as to why Hawkeye would blow up the thing he spent two days building. Hawkeye puts his arm around him: "Senseless destruction, that's what its all about. Get the picture?"
