Joke - Members who died in Service

Rabbi walks out of the sanctuary and sees the young Daniel staring at the memorial wall. He says, "Daniel, welcome to shul. I see that this is your first time here, you look bewildered, perplexed. What's on your mind? Why do you seem so confused?"

Daniel replies, "Rabbi, I'm fascinated by this wall. I love the lights and how they shine on the names, but I just can't figure out what this is all about."

"Oh Daniel," says the Rabbi, "it's quite simple, these are names of people who davened in this shul and now passed on, we remember their memories by lighting a candle on these special days."

But Rabbi, I still don't get it, what's up with those flags in the middle section? "Daniel, those are the names of members who died in service?"
In utter shock, Daniel replies: Really Rabbi!!? Which service? Rosh Hashana or Yom Kippur?!
