I've got my armor kit and am getting other parts together, so I wanted to clarify this. The replies above make it sound like you need the shoulder pouch no matter what. The CRL says:
The standard configuration calls for a minimum of two pouches:
one pouch on the left shoulder and one on the right hip.
A third worn on the opposite hip is allowed.
Option: If choosing to replicate a screen used configuration of equipment, the number of pouches may be altered.
See the MEPD SWAT page for more details.
Note: Screen used configurations also include specific color Pauldrons and individual backpacks styles.
So, this reads like I don't need the shoulder pouch without the backpack if replicating Roadblock Captain, or one of the two Docking Bay 94 Captains. Is that correct? And does it only apply if I'm going for Level 3, or is it valid for Level 1?
Thanks for the clarification.
PS: I like the suggestion of using magnets to attach the pouch without the pack!
