This came up in one of my games this past week:
A player rushed a combatant and used the Push maneuver to knock him prone. The combatant got up on their initiative pass and moved 4 spaces away. The players argued that I should have allowed a 'free attack' based on the rules for withdrawing from close combat. I ruled that the Push was not combat, just something that can happen in combat.
To be clear the player character was not previously engaged in close combat with this combatant. He ran up to him and pushed him.
So was I wrong? Should the player have had a chance to make a free attack? Savage worlds has no concept of an opportunity attack and either by accident or on purpose, they call it "Withdrawing from close combat" and the wording is rather specific about "engaged" characters.
More importantly does using Push constitute "melee" or "close combat" for the purpose pf "Withdrawing from close combat"?
A rules moderator on the Peginc forums had some clarifications about charging and fighting that can be found here.
