I’m just reading the demo pdf of TFT Melee and confused about something. If you have two figures facing the same direction with one behind the the other (let’s say A behind B)

I understand that B is engaged while A is not. The options for disengaged figures gives option b (charge attack). Would this be the option that figure A needs to choose to strike B with a readied melee weapon? Thus getting the +4 for striking from the rear?
