After buying all the 3 DVDs of the series I must say they are all great.
BE AWARE: you will NOT find hints on how to engage an enemy patrol, survival in the woods, immediate action drills and so on. If the aim is that better spend money in air-soft games and courses available allover UK.
What you will find is an overview of the situations a special forces operative will face, a general description what he will do thanks to his training, and the mindset he will use to approach them.
The DVDs are well structured with awesome balance between reconstructed stories and analysis of cases.
GUARDIANS AGAINST TERROR can be divided in 2 parts: body guard (beginning) and counter terrorism (the end).
The first will show what operatives will do in a Body guard role. The most interesting (and new) part was how to run a convoy of 3 cars in a protection mode.
The second part is what the DVD is REALLY worth!! A full reconstruction of counter terrorist mission, from the planning to the mission execution, with a view on both snipers and assaulters. Rainbow six fans... you'll love it! :)
