A mech with Wide Fork Shield will take less damage from Wide Forked attacks.
Sample: All the mechs in your front line are equiped with 50% Wide Fork Shield and the enemy mech successfully strikes your center mech with 500 damage and gets success procceeding his Wide Fork, so instead all your line receiving 500 damage, those mechs above and below your stroke mech, will receive 250 damage instead (because the 50% reduction).
