My buddy TX2Guns posted this a couple of days ago and I think it warrants re-posting more than a few times. I’ve written in the past, all the way back to the early days of the Brushbeater blog about keeping teams small in size to reduce their profile and thus survivability. You’re not a conventional force. So quit mimicking conventional tactics, it’ll get you killed. Anyway, keep in mind a guerrilla fighter does not need to take and hold terrain- he’s already from there and cannot stand up to the sustained might of a conventional force when going toe-to-toe.
Excellent primer with some historical background on some variations on what can be accomplished with a dedicated small team of guerilla fighters.
