We were given a choice as to whether we wanted to carry an M4 or a 12 gauge on jungle ops. I chose the 12 gauge. Like nighthawk, I found that it (the 5.56) didn’t have the “oomph” to get through the thick stuff in the jungle… those light, fast bullets would hit something and just deflect and go… somewhere.. buckshot must mowed through it.
A shotgun is outstanding when you work within its limitations. Still, I’ll stick with my G3 for my battle rifle…
