I’m taking a Platoon in a couple days and signing for a Stryker Plt’s worth of equipment. What advice, do’s and don’ts does everyone have?

I have to echo what another post said. VERIFY EVERYTHING!!! Then sub hand receipt down everything YOU don't need. Ex- each striker/equipment would get signed downto the NCO responsible for it who in turn would distribute it to his driver, gunner, or dismounts as appropriate.

Pull out the TM for all components associated to that Stryker. If items are missing, figure out why and if it's on order

Make sure you have eyes on and inventory your equipment before you sign then sub hand receipt it to your PSG and you are G2G!

do the work and make sure everything listed is there or accounted for otherwise you might end up with a very large bill in your name

Inventory, Inventory, Inventory. And have sub-receipts prepared for and signed by all the squad leaders and equipment holders.
Once you sign for it you own it if it is there or not.

Make sure every component of end item and all BII is there or has a valid shortage annex with the correct classification.

I agree with the verify comments. We used to use paint pens to mark the bumper numbers on all equipment, and most of it was over the etched bumper number. This stopped other platoons from borrowing items for their layouts/inventories.
Make sure you sub-hand receipt all your items. The vehicle commanders should be signing the vehicle hand receipt, and they should sub the tools/pioneer equipment to the drivers. You should do the same with your driver.
I did this throughout my career, as a vehicle commander, Section Leader, Platoon Sergeant/Leader, and Operations NCO/SGM. A full-blown TOC, with vehicles, tents, generators, tables, chairs, and 66 camo systems was a fun layout and transfer.

As a new Platoon Leader, you are responsible for Everything!
But you are there to learn, as well as Lead.
Trust your Platoon Sargent.
Don't sign an inventory you didn't Personally confirm.
Be open. Be fair. Be honest.
But you are NOT their friend.
You ARE the LT!

1st things 1st, have TMs on hand for every item you are signing for. Use the BII and COEI list to verify you have all items that are supposed to be with the end item. For instance the stryker would be end item, so you should have tools, cvcs, water cans etc. If you dont then the company commander owes you a shortage annex. Basically a DA2062 listing the items you are missing and its from him to you. This covers you so u dont ens up paying for things when u leave and transfer your books to someone else. Sign up for a LOGSA acct. You will need this more than you know. Its where you can find anything property related like TMs (ETMs) usin LIW. Another and most important thing, zero out you own HR except for what u are going to maintain posession of. For example, you should have 2 sections SGTs responsible for two strykers each. They are typically the 3 and 3 vics as the PL/PSG are 1 and 4 vics. They own the two in there section. They the sub HR it down to either DVR or Gunner or both in some cases. This ensures you are not directly responsible for the end item or its components. The next thing is any other items get disbursed through out PLT from PSG to PVT based on who uses it. This is always a good opportunity to teach property accountability to younger troops so when they become PSGs and get a new PL they can square him away since they dont teach any of this in BOLC. If you have more questions feel free to ask. I am a 11B who served az a 92Y4O for 15 months learned alot along the way.

Inventory everything on the hand receipt with the current PBO or existing HR holder. Then sub-hand receipt everything to your team leaders using the same procedure. This is SOP.
