I don't know, I mean in theory that should work, and probably has in the past, but in practice more recently I have heard from more than a few guys who try to teach things how they learned them in batt., but commanders or higher NCO's don't want to hear that stuff. Apparently its common to hear 'well that may be how Rangers do it, but we do it like this here'.
Maybe I was lucky then... I PCS'ed and..
my PSG was from 6th RTB & 2/75
my CO was former 1/75
My first task as a team leader was CQM training
Second task was class A's for company event bigger "rack" than most of the leadership, subsequent 5w description of awards *Why you have extra presidential citation on uniform Sergeant? Because I earned it, Sir*
and my nuclear option trump card if necessary was the USARAK CSM (my first CSM @ 3/75)
Another focal point might have been that the whole Stryker concept was new to everyone as well because it was a newly formed stryker brigade, and basically from the platoon level up, we had latitude to take best practices from mechanized infantry where it was warranted (long mounted movements, best ways to unass the truck), take best practices from motorized infantry *hmm wonder if Aco RSOV experience counts, yep sure did*, combine those with dismounted infantry best practices *kaching RAGNAR* and couple them together with pulling some new tricks out of our hat... or at least concepts that seemed like a good idea given we've got a multi-ten-thousand pound armored truck with a heavy MG up top. Fuck your gate, we'll take the wall; fuck your stairs, we'll take the 2nd story off the top of the truck; fuck your couch, etc.
At least at the platoon level, what we thought of them was that they were:
Light armored squad transportation that at provided
A) THIS IS NOT A BRAD THIS IS NOT A TANK DO NOT USE IT AS SUCH YOU WILL GET KILLED!
for the right mindset repeat after me, armored FMTV armored FMTV
B) A heavy weapons SBF capability
C) a good amount of increased SA with the electronics
D) Shelter from weather during transport, WITH a fucking heater *shivers thinking of some RSOV rides*
E) a ride to close to the fight so we showed up better rested and in a jolly mood to go kill shit vs pissed at our kidney pad or what have you
F) Your own perimeter security via 4 big f'ing gun trucks w/ crews
We knew the tires would burn. We knew the fuel tanks would burn. We knew it could roll over. We knew all these things and trained on them (thanks to the mech elements we had as NCO's) on getting the bailout hatches open under all circumstances (and keeping your gear combat effective yet slick enough to not hang up). Manually dropping ramp. Getting the driver out and taking over if he was hit. What to do for a fire. All the different NEW battle drills inherent to not only vehicular operation but THAT vehicle's operation.
Not to mention that basically every NCO in the unit had combat experience of some sort at that point, the other PSG's in the company as well (one had been an RI at 5th RTB, and one was with 10th Mountain.....in somalia) and there was a huge amount of crosstalk regarding "we KNOW we are going to combat and we WILL train right, hard, and the right way, to give best probability of 100% return" so further/faster/harder was the order of the day, every day.
Anyway, basically I would have to surmise that it's situational dependent with regards to being able to apply knowledge from Regiment. I probably had a perfect storm to be totally honest, but all my friends who have PCS'ed as well also have found good niches where their knowledge is applicable and have few complaints. At a minimum, their guys are squared the fuck away even if the institution above them is in full retard mode.
