After VE Day, Eisenhower was showing off flail tanks to General Zhukov, who remarked that he just marched infantry to clear mine fields.
Interesting candid point as to how much the Russian military valued their soldiers' lives.
Khomeini did that with pre-teens in the Iraq-Iran wars, sending them in before the infantry to clear the ping mines. That caused a lot of them to be blinded as the mines were designed for chest-high bursts on adults, not face-high for the kids.
