WW1, the war with the most stupid tactics. Send thousand of men into machine gun and artillery fire and hope some survive to be captured by the other side.
In the battle of the Somme the British did just that, to force the Germans to transfer troops from the attack on Verdun to the Somme. It worked; despite horrific British casualties (60,000 on the first day), Germany had to divert troops there and the French survived at Verdun.
Today few Westerners want to fight in wars because they know their lives will be thrown away by their governments like that.
Except for the machine guns, not much different than Lee’s assault on Cemetery Ridge at Gettysburg, or Grant’s assault at Cold Harbor. Thousands of soldiers lives thrown away for zero results.
