Good day monks. I'm trying to regularize references to U.S. government entities in some text. Taking the U.S. Army as an example: 
$text = "U.S. Army\nthe Army has been berry-berry good to me\nUS-Army\
+nUS Army\n";
$text =~ s/\bArmy\b|U\.S\. Army/US-Army/g;

This yields the following 
US-Army
the US-Army has been berry-berry good to me
US-US-Army
US US-Army

[download]
The last two entries are obviously not what I want and they are happening because the dash counts as a boundary. This is even worse in the context of a loop like 
while ($text =~ s/\bArmy\b|U\.S\. Army/US-Army/g) {
    print "$text\n\n";
}

[download]
which results in an infinite loop. So my question is: How can I get the dash to not count as a boundary character? (because of external constraints, it's not possible to use another joining character).

Many thanks in advance...

Steve
