here is a link to a nice promotional video about the three major infantry brigades of the IDF.
the sounds in the video arent authentic (such as a mk.19 sounding like an M16 on auto.) but its still intresting.
keep in mind the movie is a few years old and doesnt reflect the major upgrades in infantry gear that took place during the low intensity conflict that began on october of 2001.

Cool. where is there snow in Israel?

during the winter snow falls in the Galilee, Ramat Ha Golan and the Jeudah Mountains (where Jerusalem is).

Is this all footage of training or is it real encounters?

I ask as towards the end there is an escort convoy that comes under attack. The man appears to surrender and the troops set a dog on him and he is wearing no protective gear at all. Not a position I’d like to be in

its a training scenario.

don't know why the guy has no protective gear but you can see that the dog doesnt bite him and when he falls to the ground the dog leaves him.
