You might be interested in reading about some of the tactics used by the Soviet armies in World War II. Here's a short description:
Order No. 227: Stalinist Methods and Victory on the Eastern Front
Especially interesting are the penal battalions and blocking detachments.
Russia has a history of winning wars by attrition and so did not shy away from tactics that leveraged their advantage in manpower regardless of the losses suffered in their own ranks. Putin seems to me to be enough of an "old school" Russian leader to continue these kinds of barbaric approaches. But I hope I am wrong...
I was reading my dad's memoirs last night and came upon this passage. He's describing his experience as an officer in the US Army during WW II, in Burma. China fought with the allies against the Japanese:
The method of procurement and enlistment of the general run of Chinese soldier was something no one of my acquaintance could attest to personally, but
“everyone in the theater” in Burma would believe the following story as completely true.
At a particular time in any village or town in China, an area would be cordoned off and the “noose” tightened and all men were apprehended and were conscripted into the Chinese army in Burma. I suppose the very young (children) and the obviously old or crippled were released but the rest were rounded up, the door sealed—everyone standing, cheek by jowl…no food, no water, no oxygen (except in the flight crew’s sealed cabin) and the planes took off for Assam, India at heights in the neighborhood of 14000–16000 feet over the lower Himalayas and out of the known flight paths of Japanese aircraft. Mostly they flew at night. Upon landing, the doors were opened, some of the “conscripts” had died from suffocation, and were quickly disposed of—the rest were in the army, if they could stand. They had never had any kind of training or orientation. They were given rifles and had a modicum of training in their use, but little else, and back in China no one knew what had happened to them.
