I’m building a Merkava IV. I can’t figure out how the 0.50 cal machine-gun is connected and where the wires for the machine-gun to gunner/commander seat goes. I can see, what seems to be an electric wire goes from the back at the .50 cal and ends where?
Someone has some pictures? Google can’t help. Please help, thanks.

Thanks for asking this question Carsten! I was going to be asking the same thing here soon.
Thanks Israel for the awesome photos they will be put to use here soon.

Agreed, great pictures of the back up, manual charging and firing cables. My question is since there are electrical solenoids mounted to allow charging and firing via an electrical circuit, where do those cables (visible below the .50 caliber MG in the bottom picture) enter the turret?

I need to do some digging, I do remember seeing a picture of it somewhere...

Great pictures, thank you, absolut useful. But I still can’t see how the thick black cable are connected to the 0.50 cal. Also missing where the cable goes inside the turret. In some pictures it seems that the cable are running in a tray, and sometimes the cable lies “loose” at the turret roof.
Thanks again.
Thanks again.

it looks like the cable runs down into the gap between the turret structure proper and the applique armor module and up underneath the solenoid mount before branching off to the two individual solenoids.

I tend to agree with you, although in the second picture it seems to 'disappear' into the storage bin just front of the TC's sight.

Thank you, for all your time and all the pictures, very helpful.
Time for detailing, this mechanism in scale 1/35. No excuses.
Thanks again.

So what's the actual purpose of the .50? Just a heavy coax weapon or is it used as a last-resort aiming device, firing tracer on the same ballistic trajectory as the main gun?

20 years ago we used to use the .50 cal for a single purpose only: simulating the main gun up to max. 1.500 m in certain drills. We always removed them before operational deployment.
These days they seem to be permanently fixed. I guess apart from using them the same way did, they're also an additional, beefier coax for engaging targets up to around 1.000 m.

Israel,
Thanks for the additional pictures to clarify where the electrical solenoid cables "disappear" into the turret.
I know that the US Army mounted the .50 caliber MG to give the tank crew another option beyond 7.62 and 120mm weapons to precisely engage targets with the gunner's thermal/FLIR sights and controls.

Hi John,
Exactly. I think both armies came to the same conclusion due to the asymmetrical warfare they were (are) fighting.

Strange, I've seen pics of some (not all) IDF tanks in Lebanon back in the early 80's with .50's mounted so I assumed they always had an operational role.

I can't tell from looking at the pictures myself but would anyone like to hazzard a guess as to whether the ducting is tubular or box cross section?

Thank you for posting those close-up photos of the .50, there seem to be 2 variants of the trigger mechanism shown, wasn't there a 3rd style also?

John,
I'm not sure if there are more variants of the remote charging and firing that the manual set up and the one that uses the solenoids to charge and fire the .50 caliber machine gun. There is sometimes a cover added to protect the solenoids but I would surmise that the mechanism underneath is the same.

Most of the Merkava Mk.1s didn’t seem the have them, Magachs and Shots on the other hand show a more mixed picture. Could be that regular armor units did have them while reserve formations didn’t (this is the situation today; some Mk.4s in reserve don’t have them).
I think the whole thing has something to do with asymmetric warfare in urban environment. Between the end of First Lebanon War (1985) and the beginning of the Second Intifada (2000) the IDF probably thought that such warfare is unlikely to happen therefore didn’t bother to mount them. Just guessing here, I could be completely wrong...
