Currently I'm training to be a Scout Leader, I'm in the tactics phase of ABOLC and I cannot tell you how much stuff there is that we have to focus on. By Doctrine and not necessarily practice when ME is halted CAV set up defensive screen lines, however they conduct recce in zone when the ME is advancing. That's doctrine, LRS units missions are much different they're out there much further ahead of CAV Scouts where only CAS and CCA have a chance of supporting them if they get into it. But like CAV Scouts their best weapon is the radio, CAV Scouts are supposed to be sneaky and not get engaged beyond their capabilities.
However, based on doctrine within Cavalry Squadrons and their Cavalry Troops they have Reconnaissance Platoons. The FM that Reconnaissance PLs operate out of is titled FM 3-20.98 Reconnaissance and Scout Platoon.
The BFSB Cav Squadrons have a cavalry troop and one LRS Troop...what I don't understand is how they're all from the same Regiment but are MTOEd as ABC troops...makes no sense to me at all. Another side was a guy in my class was like hey I'm going to this unit they has a LRS Troop can I get these schools...blah blah blah. That is neither here nor there...but when I began reading this it seemed like an appendage measuring contest.
They're are plenty of 19Ds around here that would beg to differ on the opinion that their job is useless and calling it such is disrespectful.
There are actually 2 CAV Troops in the R&S Squadrons under the BFSBs.
And there has been a lot of confusion with the MTOEs when they brought the LRS Companies under the Squadrons and adding to it several were allowed to keep their lineage!
