Cobras are a good choice of model for Battlefield TAG Outdoors because they are very weather resistant. However, you want an even smaller model then you could switch Cobras out with the Blasters.
The Battle Boxes are a versatile battlefield prop, you can set it as a combination of Medic/Ammo or a Flag Box or even a Target Box. We always recommend ordering 10% more gaming guns than the number of gamers you plan to cater for. Operators also need to order a set of red headbands and blue headbands for each gaming gun. (Basically 50% red and 50% blue.) With the extra battle boxes, gamers can play both 2-point "Capture & Hold" and electronic "Capture the Flag".
Plus operators will need a set of red and blue bandannas (a multiple of the number of gaming guns in your arsenal depending on your day's throughput).
Plus one spares kit or every 10 units ordered.
