US tanks have fallen far behind Russia in a key area
In 2006, Israel sent its top tierMerkava tanks to fight against largely unarmored Hezbollah divisions, but they still faced considerable losses owing to the proliferation of advanced antitank rounds, many of which originated in Russia.
Fast forward to the 2014 Gaza conflict with Hamas. Despite Hamas having similar weapons and backing, not a single Merkava or Israeli armored fighting vehicle was lost. The reason being that Israel had perfected the Trophy Active Protection System (APS) to defend its tanks.
