I ask again, how is getting blown up by a mine worse than getting blown up by a bomb or artillery round?
Mines that can be set off by humans are anti-personnel mines, (anti-tank etc. tend not to allow themselves to be initiated, (read: wasted), by a human. Anti-pers weapons are designed not to kill and, often, not even to do critical damage. The aim is to maim as badly as possible to ensure that the man does not come back to the fray, ever. This is because a dead man takes two men to manage, (they dig the hole, document him and drop him in), the death, (I know there's more to it than that nowadays). A severely wounded man takes up a lot more assets. The intent is to bog down the B echelon with people going backwards and the amount of time and effort expended on them.
Bombs and Artillery rounds are designed to explode and cause the maximum damage possible... A close call with one of these is usually fatal.
