I think this almost what you want ... 
#!/usr/bin/perl -w
use strict;

$_ = <DATA>;
my @matches = /([A-Z].*? )[a-z].*?/g;
my $biggest = 0;
my $biggestCluster;
for my $m ( @matches ) {
    print "$m\n";
    $_ = $m;
    my @cs = /([A-Z].*? )/g;
    if ( $#cs > $biggest ) {
        $biggestCluster = $m;
        $biggest = $#cs;
    }
}
print "Biggest Cluster is [$biggestCluster]\n";
__DATA__

+to Buenos Aires. There were the predecessor of the modern AH-64D and 
+AH-64D Apache.

... it has a problem picking up AH-64D Apache, but hopefully you will still find this somewhat helpful.
