Shooting a Bren 100-Round Drum - YouTube
You'd want those when you have the Motley chair... He's smiling because of the ammo he's about to go through. No hearing protection required...
Raised sights eh? I don't recall ever seeing mention of raised sights being made for or available for the drum. Surely, if such were available, they'd be part of the drum kit. I always thought that aiming - such as it was - with a Bren was with tracer, aiming a 13 apparent aircraft lengths ahead of the aircraft
Sights are between the TWO guns on the Motley mount.
No provision for an AA sight on a single ground mounted gun.
Thought so. But on the stand-alone AA tripod it was sightless, using tracer. I liked tracer with the GPMG and the Vickers. Used to load the last 10 in the belt with tracer just to show the gun crew that the belt was running out. It also served as a reminder to the observers just how close the rounds were following each other. It was one thing seeing 4 ball x 1 tracer - where you could only imagine the ball, but quite something spectacular to see 10 tracer in one stream
Loading the last 10 or 20 rounds of tracer was a good trick.
It was absolutely amazing to see the flight of the tracers.
It looked like a laser but the the ones that took off at 90 deg. were also interesting.
About 1 in 4 seemed to have a mind of its own and took off at a totally different trajectory with some leaving the line of fire at almost 90 deg.
Usually indicating a shot out barrel. When a barrel is good they go where they should...Quote:

But as BAR says, when a new set was fitted, the cone of fire would literally boil the sea. AWESOME - and I wasn't paying for the ammo
In WWII fighters had trace to indicate ammo was running out not sure how far from the end of the belt, one instance a squadron well they stopped the 1-4 ratio as the tracer clipping past an enemies wing tip gave them the visual they were being fired at. When they ditched it and just went to incendiary & ball mix rather than trace air to air kills went up as the enemy fighter pilots first inclination they were being fired on by another fighter is when the business started banging their plane apart. As there was no visual signal indicating incoming fire........
Nice to warn the opposition that you are running out of belts, firing only tracer at the end.
Not as simple as that Dan........ The unfortunates on the other end of the incoming can't see the tracer and even if they can, they know that as soon as the 81's get the map coordinates, they'll be on them next. We call it '.....the chop-chop' as in bad haircut day!
Watching a Sustained Fire Machine Gun platoon shred the scenery gives you something to think about. Eight or so tripod-mounted GPMGs firing in sequence into a target area that can be the size of a football field at 1500 metres or further. This is not "precision shooting", more like area denial. The basic 7.62 NATO tracer burns out somewhat short of that distance, about 900 metres, but SF guns are sighted by "survey" techniques, not by squinting through a cranked up ladder sight.
In common with mortars and artillery, they are also controlled by a Fire Controller who is observing the target from a hopefully safe spot outside the arcs, somewhat closer to the impact zone; see also Mortar Fire Controller. The trick is that the guns fire bursts in sequence. This allows each gun to rest a bit between bursts and also allows the crew to reload, swap barrels and adjust the traverse and elevation for their next turn. This produces a steady stream of fire that is moved in a precise sequence to cover the target area
Such a shoot at night is spectacular if it includes tracer. Without it, there is just a lot of noise accompanying the glow from the night sights and "barber's poles" and the muted muzzle flash. Then again, the last shoot I attended as an observer / safety crew, they stripped out the tracer for the qualification day and night shoots, because during the "training" phase, the stuff kept setting fire to the dry scrub down-range.
Since Radar and passive acoustic locating devices started to become common on the battlefield, SFMG operations have become more subject to counter-battery fire. Medium and heavy mortars deliver a greater weight of unpleasantness much more rapidly than a flock of machine-guns. Cover that will shield you from high-trajectory bullets may just not cut it when 81 and 120mm mortar bombs start falling from three to five times the distance..

I certainly copied one of the DDEIP and probably the DD(E) but unfortunately I don't have access to thousand odd Sheets I copied back when the Pattern Room Library was MoD run. The back up discs are so buried It would take weeks to find them. However I did share the lot with various folks so if some one could step in and put the images up...?

PS I also copied the drawings for the various sights that fitted onto the mountings rather than direct on the gun and those for the Motley and Straddle and they were kept in separate files so I do have access to them.
Interesting. No wonder that we'd never seen them. Introduced and declared obsolete on the same day. You have to do it that long winded way to bring the item onto the VAOS list and codify it before you can declare it obsolete otherrwise you end up with a backlog of obsolete kit which the blanket stackers can't get rid of.
It does seem very late on to introduce such a sight, given that the drums were pretty much obsolescent by then
