Thank you. Don't you hate to read "deep" preachy analysis from someone who can't even be bothered to learn the fundamentals?
On another note, critical thinking is dead. This writer announces the demise of heavy armor because of the availability of light shoulder-fired anti-tank weapons. What he doesn't explain is how the proposed lighter replacement systems won't suffer from the same vulnerability.
The only way to reconcile this is to assume we'll return to the Sherman method - make too many of them for the enemy to kill them all and accept the human losses. Unlikely in this era of casualty minimization as a priority.
Because the Iraqi armor was devastated, the Age of Heavy Armor is over. AHA!
Given the lethality of tank countermeasures, and a US reluctance to absorb heavy casualties, expect to see more robotic flying/crawling platforms. They could be controlled from well out of range of enemy fire, and could be mass-produced in quantities that make losses tolerable
Just as the battleship gave way to the carrier and its airplanes, the tank may give way to an armored command vehicle controlling swarms of remotely-piloted weapons platforms
