Since many USAians are now or in the near future going to be interacting with citizen-soldiers in ways they never have before, I thought it useful to post a link to an archived version of the US Army's Soldiers Manual of Common Tasks (levels 2-4) . Every soldier gets a version of this manual and uses it as a guide. While updated, it is much the same manual I was issued when I enlisted way back in 1989.

Subject area 19 - Crowd Control could be of immediate interest to some but the whole manual is worth a read

..and the link for the skill level one manual
