Day of Days - S1-E2
Audio problem: When Easy are attacking the 88 battery, in the scene where Buck scouts out what's ahead of him before throwing grenades, you can see a soldier holding an MP40 (machine pistol), who fires one shot with the sound effect of a Kar98 rifle. (00:31:50)
Answer: To mess with him. A lot of the "regular" soldiers didn't respect or even like Webster early on because he was a college boy. That dislike and lack of respect was deepened when Webster took what they perceived to be an extended stay in hospital after being wounded when many of their other comrades - Popeye for example - left hospital early to get back with their friends to fight.
He couldn't leave hospital early because he was in England. The wound in Band of Brothers was perceived a lot less serious than it was, and a lot of easy men were happy to have him back, especially Luz.
If you read the literature around Band of Brothers, you'll find that Kenyon Webster was perceived as a slacker in the sense that, while not precisely a coward, would never volunteer to put himself in harm's way. He only did as told and nothing more. So, regardless of the reasons why he really couldn't go back to Easy, his friends were predisposed to feel he was slacking off at the hospital while they were risking their lives.
