This replay makes clear that Salo is an UBER EXPERT. I mean most ordinary experts would not have the audacity to charge deep into the FOG OF WAR at 39:50 with a 20% health KT and 2 paks without any infantry support. Particularly when US is known to have at least three rifle squads. That KT is an irreplaceable mega weapon which would be trapped prey to a single rifle squad with a sticky. Most players would immediately reverse it to safety and get it back to health.
Advanced tactics and sheer bravery allow Salo to plant the damaged pak at 39:59 along with the KT which stops its advance -- before the Pershing is revealed. While the full health pak continues a few more paces revealing it at which time both paks and the KT open fire. UBER EXPERT move risking a one-time call-in that's nearly destroyed in order to MAYBE make the US player waste 200 ammo activating allied war machine.
