In CatchBob, we are interested in an activity (depicted on the figure below) that fits 4 constraints:

space constraints: the activity occurs on the field, people are highly mobile
time constraint: the activity does not last very long: few hours maximum
organizational constraint: decentralized team (with no operators at a upper level in a control room)
communication constraint? no audio communication (noise in the background…)

Apart from military stuff, are there any other activities that fits those constraints?
