If you have some time to burn, just came across this documentary which is part of a series. I cannot comment on the series, but I can comment on this episode.
Title: The Lost Platoon.
By: Dan Reid.
It was part of a BBC series called "Our War" and is Series 2, Episode 3/3.
For one hour you follow 7 Platoon of the UK's Welsh Guards in their outpost in Haji Alem, Afghanistan in 2009.
Some good (and hard) lessons learned about being a platoon commander / platoon Sr. NCO, equipment redundancy, first aid training, communication under contact, radio drills with higher, efficient medevac / casevac system, etc, etc.
Worth the time if you have it.
