In the following sentence
The clams, which he ate, were

This clause gives more information about The clams, which means it has the function of an adjective: it's an adjective clause.
I would say: all of the above.
In the first case: if the prisoner didn't do anything wrong, then they should not be tortured for information.
<em /> In the remaining cases: this would mean destroying agriculture and culture of the enemy, not their military, yet it is the military that is probably the true object.
