@Chinmoy Sir,

We are unnecessarily getting / migrating to "Grenade 36 M Hand and Tube Launching". I am sure both are same so far tube launching is concerned. It has a base screw and the bottom of the base screw has female threaded portion to take in the launch tube. As I said earlier, the grenade is requires to be primed with different 7 second fuze and an iron ring is inserted over the safety liver before firing, It requires a ballistic cartridge to fire it from 7.62. It is cumbersome and time consuming alright but not what you are claiming.

Let us get over it and move forward.

GRENADE 36 M HAND AND TUBE LAUNCHING



PRINT DOCUMENT

This is an anti-personnel ammunition of fragmentation type, generally hand thrown. However, it can also be projected from a Rifle 7.62 mm 1A1 fitted with projector grenade 7.62 mm 1A using Cartridge SA, rifle grenade 7.62 mm HD. (TUBE LAUNCHING).

The grenade has a range of 23 to 27 metres when hurled manually and an increased range of 183 metres when fired form a 7.62 mm rifle. It explodes into 40 to 60 fragments, killing and maiming the enemy within an effective radius of 27.5 mts.

Specification :
Grenade body Cast iron, segmented externally for better Fragmentation
Explosive TNT
Detonator 4 second delay (hand grenade) and 7 second delay (rifle grenade)
Mass of grenade Hand 680 g
Rifle 802 g

Packing :
Ten grenades are hermetically sealed in a steel Box and four such boxes are packed into one carrier. A total of 40 grenades per package. Average gross weight is 53 kgs and the package dimensions are 660 mm x 325 mm x 215 mm.

I believe the 36 M rifle tube would need blank cartridge to be fired. The one in Shivalik has bullet trap technology allowing live munition to be fired.

36 M grenade needs a separate blank cartridge + 7 Second Fuze + Iron ring + adapter firing attachment for barrel of 7.62.
If 4 Second fuze is used there will be an airburst of the grenade at 4 Second which has its own uses.

Due to these, a dedicated "bomber" is required to fire 36 M Grenade. One soldiers amonst ten is nominated and equipped to a "bomber".

For Shivalik Certain things are not clear :

How can the Grenade travel 200 meters when fired from a rifle launching tube as time of fuze is only 4 Seconds ?
Will every Rifleman be able to fire rifle grenade ? Safety ring provided and normal ball round used for firing ?
Any air burst technique ?

Normal ball ammunition will be uaed. Rifle grenades tube is secured with a safety ring.
The Shivalik fuze has been designed to function on impact at all angles. Detonation on impact is also a feature of French AVAP40 and AC58 rifle grenades. These French grenades can be used at different ranges from 60 to 320 m.

@Kay .. I am sure you have never held a grenade in your hand.

For firing grenade from a rifle a cut Iron safety Ring is fitted on top of and around the grenade, on top of safety lever, with cut portion of ring at the backside of safety liver. Before firing the Safety pin is removed .On firing the safety ring is pushed backwards and comes out, safety liver is released and charge initiated. Safety ring has nothing to do with launching tube as you claim.

You are right. I am that pesky keyboard warrior getting all my information from internet :).
I tried to answer some questions you asked. I had a rough idea of what you said from DRDO website, but you explained it better. I was assuming the ring at the base of the grenade to be the safety ring, but your illustration makes things clearer.

I am surprised that you are questioning the terms offensive and defensive grenades - because they seem to be common army parlance and not something DRDO invented for marketing practices.

The fuze has an impact mode as well (at least as per DRDO), so there you go.
Will every Rifleman be able to fire rifle grenade ? Safety ring provided and normal ball round used for firing ?

I'm more concerned about the comparatively smaller amount of explosive filler used in this thing.I mean just a hundred gms??!!Like, for real??!!

Kitna deti hai ?
Kitne ki hai ?

Specifications ??.

Andar ka maal kahan se kharida hai?
BOSS is totally indigenous in material aspect. As far as specs is concerned, please find it below.

It was deployed as a pilot project in LOC and LAC, so no commercial pricing available as of now.

Thank you Sir.

I was on one of the first introduced BFSR on LC (run with Microsoft Windows programme).
That used to give all false indication even on blowing wind or a tree swaying due to wind.
No distinction between an animal and a man. lots of running...
So we had to pack it.

I hope those faults have been removed.on Doppler processor and MTI. I also hope that it is not used only as a thermal imager.

Even we faced those initial issues. Good thing is that within the timeframe, most of them were rectified. Hopefully now its working fine as we could see its cut down versions in some tanks too.

Answering is more important than understanding ? is it ? First understand ....
If I fire a grenade from a rifle - it will gain a certain trajectory and then reach 200 meters away. Will that be reached in 4 seconds?
If not the grenade will be initiated in 4 seconds while it is in trajectory - that will be airburst and might be unsafe particularly when the firer is in open.

In 36M grenade one had to use 7 second fuze for rifle launching.

That is why the question.

Not much of explosive is required if kill radius desired is 5 meters. What is more important is the number of fragments the blast will generate.

SCAR Ls.
SCAR Hs.
Mk49 LMGs.
Mod Deus HMGS (YESSS) for mounting on LSVs (those Force Gurkhas)
NVGs (quad tubes please)
Some other stuff.
AND AMMO. tonnes of ammo ( because, YES OFB ammo is that patchy)
Hopefully, we get more details on the NVGs, Optics for the SCARs and comm sets would be good too. Fingers crossed.

I thought grain consistency, size and weight was important for sniper ammo only, may be for pistols too. For spraying the bullets around Indian OFB mal is ok.

Why NVGs ?!! Tombo is making quadtubes in India now. We don't need to go the amrika for optics

OFB 5.56 is overcooked. Too much powder. It has caused several Tavors and M4s to crack wide open. And many INSASes too, now that I think of it.

I don't know either, given Tonbo makes good quality stuff;

One complaint that I have heard that Tonbo's offerings are not of MIL-SPEC - they are fragile. A rough bump or two and the electronics get screwed.. they are working on it; in the meantime though....
