salient corner การใช้

• The " de-sumis " ( salient corners ) on the north side of the " hon-maru " are rectangular flanking projections which increase the castle's defensibility; the " iri-sumis " ( receded corners ) on the south side of the " hon-maru " also increase the castle's defensibility because they permit cross fire at the enemy at the southern corners of the " hon-maru ".
