No, it is a CIP (Combat Identifier Panel), it folds up to “turn it off” so it is not seen in thermals.
They are on both front slopes of the turret, along with the sides and rear of the hull. Below you can see both turret CIPs open, they appear as darker rhomboids.

It’s a Combat Identification Panel.
Thank you for a quick response 
Hi!
Does anyone have a closeup photo of the ERA bracket mounting marked below? I’d be extremely grateful. Thank you. Luke
Welcome to the forum!
Not a close up. Just a similar photo of about the same fidelity on a Bradley in
Syria. I’ve been working up the entire lower array as seen for the Bradley in this thread.
As you can imagine, it’s taking a while, hence no updates.
Oops, no photo of the Syrian one in this thread. There’s another, but no time now.
Thank you very much!
This is one I happened to have on my computer. No wifi where I am and only one bar on my phone for tethering.
According the the Caption I put on it, it’s Ali Al Salem. Anyone who’s been there knows how much it sucks. But I believe all of these Bradleys were on their way to Syria a few years ago. I’m using a jig for the armor plates. The ERA brackets are available in PE.
The hardest part is the springs. I’m using copper wire twisted together and then wound around a drill bit.
That’s really helpful, thank you. Would be nice to know what shape those boxes with springs were actually 
Each one appears to me to be a long, square prism with four bolts on top. That’s what I’m going with.
You can get some good ideas from this video:
The inspiration for my load out diorama and all of the scratchbuilt items comes from these photos:
There will be an SF straphanger off to the side inspecting his sniper system.
use both hands when you hang on for dear life, my guy. 
The term “strap-hanging” comes from Airborne Units within the army. It refers to the practice of showing up to a parachute jump, for which you are not scheduled, in the hopes that an extra chute becomes available . Individuals who make it on such a jump are known as “strap-hangers”
HOWEVER!
In this sense I mean a dude who’s just going along for the ride.
Goes back to the days of SF in Vietnam. I’ve been a straphanger with 3ACR. Beats walking all the way to OBJ, And back. But they had nothing to do with the mission.
In my line of duty, we call them “Ride-Alongs”.
Wow! Hard to believe this picture is little over 2 decades old. I’m feeling that one. 
Yes

The bottom photo represents the older style of mount for the spaced armor plates, which was sort of a "Z’ shape. Soon after, those mounts were replaced be the cast blocks you see in the upper photos with the rounded cut outs for the mounting bolts.
Older Bradley kits have captured both of these styles. The newer mounts are necessary to pull off the look of the newer spring mounted plates
Gentlemen, I have a question. Does M3a4 really exist? and if so, what are its differences for the modeler? There is an idea to remake M3a3 Meng in M3a4, using the some detail from M2a4 Magic factory
According to wiki
The M3A4 model of the Bradley is fitted with a new 675 horsepower (503 kW) engine. Electronic systems have been improved. Deliveries of upgraded vehicles commenced in 2020
I took this photo today at the train station. Only Bradley’s were this color; the rest of the vehicles were sand-colored.
V.Z.
Yes, they exist, as noted above, they were fielded alongside M2A4s. They have the same basic changes as the M2A4 as outlined below.
If you add all the Magic Factory A4 parts (B Sprue) to a Meng M3A3, you will have an M3A4. You will also need to add the T161 tracks and sprockets to go with them.
Another option is to get the Magic Factory M7A3 kit and add the A4 parts from their M2A4 (Sprue B) to it. The M7A3 is based on an M3A3 hull with the M3 TOW reloading hatch and rear periscope setup. I plan to do the same thing.
