Sorry, soldiers aren’t toilet plungers. Couldn’t you have thought of a better analogy for people who risk their lives to protect Yidden (no matter what their motivation might be)?
Your analogy to sports teams is a pretty good one – some people wear those sweatshirts to show support for the team displayed, and some (although certainly a minority) simply because it’s stylish or because they received it from a fan or bought it in the local thrift shop.
