Could Israel's 'Tank Shield' Make the U.S. Army's M1 Abrams Even More Deadly?

It's a possibility.

It's about damn time

I expect so CW5 Jack Cardwell since Israel is one of the few countries with very advanc3ed development and manufacturing capabilities. They have modified our aircraft and ground-stand what what they need for short and mid-term capabilities.
