attritive

These rock types' medium hardness means medium resistance to abrasive and attritive erosion.

War comes not when it is made by sovereign against sovereign (not when killing for attritive and strategic neutralisation purposes is authorised; nor even, properly spoken, when shots are fired); rather, war comes when society is generally convinced that it is coming.

Some observers believe that the Vietnam War was a necessary attritive component to this war - Soviet industrial capacity was diverted to conventional arms in North Vietnam, rather than development of new weapons and nuclear weapons - but evidence would need to be found that the then-current administration of the US saw it thus.
