Place something in your pocket or take a bag in your hand and start walking. Have your partner come at you as clean from intention as possible and have him work to get the gear off you and run off. You choose in this drill to work to keep the gear with you and move accordingly with no limitations. Have one of you with a knife hidden on him in a pocket or somewhere else and as defender check if you remember the blade and if you are able to use it and as mugger check if you can use the knife past the point of contact without loosing the purse. Later on you can do the same drill using a bicycle and so on and note later on using either your briefing or another partner what was you field of vision and your feeling during and after the drill began.
