Martial Maneuver - Kick

Prerequisite: Fighter, Bard, Paladin, Ranger, Rogue

When engaged in melee with a single opponent (within 5 feet) that is medium or small size, you are keenly aware of the flow of your attacks and as a bonus action, can kick out with a foot to your opponents chest or leg, sending your opponent staggering.

This is a melee attack counts as a bonus action, can only be made after primary melee action(s) have been made, and requires a roll to hit.  Applicable modifiers are your proficiency bonus and your strength or dexterity bonus. On a hit, the damage is 1d4 + strength modifier and your opponent must make a Maneuver DC save of 8 + your proficiency bonus + your Strength or Dexterity modifier combined or be shoved 5 feet away and falling prone.  This eliminates Attack of Opportunity from that opponent.  On a successful save, the opponent is shoved 5 feet away and their speed is reduced by 1/2 on the next turn but they are not prone.
