Glad they’re adding a Humvee to the game, though I decided that I would give my opinions on the model and my observations.
First, the generator on the back is a 10kW generator. I’ve never worked on them but I have seen them around.
The 10kW

The next thing I noticed were all the cans in the back. For some reason, they are all water cans. And there are 10 of them!!! Is this crew really well hydrated? Does this generator run on water? What could I be missing here?
Water

From the driver’s perspective, the mirrors are really well-adjusted. Technically you don’t need to have the right side mirror out there if you have a reliable TC.
Mirrors

The doors themselves are the non-ballistic doors. The latches are a pain (not as bad as the cloth doors) and the windows can be hard to move depending on how old the doors are.

Into the engine bay, the entire generator is missing. Like, the washer tank and pump are there, but not the generator? How does it generate power?

This one is kinda bad. The gauges are basic and don’t have the correct graduations, with the battery not even close to what it should be. The speedometer is sitting at 35 mph while parked (we’ll get to this later) and everything is sitting far below the stopping point for the needle. Also the high beam light is orange instead of green.
The dash to end all dashes

This part is strange. First of all, the parking brake is engaged. Then on the right, the transmission shifter is set to neutral. Not exactly a great combination, but even though this is supposed to be the M1097A2 it doesn’t have the newer transmission selector so it gets a pass for now. that’s not the worst part. To the left of that, the transfer case shifter is set somewhere between high and neutral, which is a great way to make magic confetti.
How to actually not park a HMMWV

Excuse me? What did you call me?
WHAT???

The passenger side does not have a NATO cable receptacle, so it cannot be attached to another vehicle to charge.
Seat

On top of that, there are no batteries under the seat. So, with the water-generator, the lack of a generator, and no slave cable receptacle, the HMMWV has no power at all.
No charge

Oh and there’s no horn as far as I can tell.
Hornless

This part is fun. First of all, the ignition switch is upside down and I have no idea what it’s supposed to be on here. Second, it looks like the words are “ELR, HELP, SPIN” which is kinda funny. The light switch has the lights off entirely, which isn’t out of place in War Thunder and also a good way to not waste the battery that this truck doesn’t have, plus the settings on it are incorrectly spaced and it’s missing one position entirely. And the parking brake indicator is orange instead of red.
Light switch of fun

Off to the right we see the indicator switch, which is missing the hazards tab, and it is also not green enough. The air filter restriction indicator is also wrong entirely.
Indicate this

Speaking of indicators, why are the lights red? Why is just the center orange? Why are there prominent circles in the middle?
Circles

Why the circles???
Circles!!!

Those are all of my observations for now. I can’t do this with the actual M1097 that carries the missiles, but I’d do that one too if I could.
