This loadout provides decent flexibility and the ability to split into 2 teams of 2 for coordinated strikes or handling two rooms in the same hallway, etc. It has lethal weapons up front and the option for LTL weapons if the situation calls for it. I allows for auto breaching with shotgun when doors are locked but the team wants to preserve dynamic mode. It allows for at least some control of the environment with wedges, and some intel gathering from optiwands.

There are many possible loadouts, but this one is a pretty good starting point. As always, the leader may alter this based upon the mission needs.
