It's not so much about the tank, it's about the crew inside the tank and how well they work together as one.

Interesting comments on loading timings based on loader breech circuits. On older tanks, The firing circuit only completed when loader confirmed breech guard closure and the gunner then depresses the firing trigger. A trick would be to have gunner maintain aim and have trigger depressed so loader would be "trigger" when he closed the breech guard. This saved valuable milliseconds but required loader to know to stand out of way of breech!

In my military career, I crewed an M-48, M-60, M-551, and M-1/a1, it is exciting in the turret during live fire. The most dangerous was the M-551 with the combustible cartridge case. That was a nightmare as the obturator seal had a bad habit of sticking in the breach and falling on the floor. If you did not see it, the next shot was with an open breach inside the turret! I was range safety officer during night fire and had a tank fire in that condition. Flames came out of the loader and TC's hatches. Really bad, casualties, but no fatalities.

@ispycyanide The casings are made of a mixture of cellulose, nitrocellulose , resin and a few stabilizing components and burn up completely when the round is triggered. Only the bottom plate , which is made of steel, remains and gets pulled out of the barrel by the breach once it opens again. You can see it fall down in the video. This saves space, weight and time.

A CITV is a Commander's Independent Thermal Viewer. The thermal screen in front of the commander's station is what allows the TC to see what the gunner is seeing. The M1A2 SEPS is equipped with an independently-revolving thermal viewer that allows the TC to scan separately of the gunner, and designate targets upon the gunner's engagement of those targets. In short, the TC scans and brings the gunner onto the next target that the TC identifies.

That's the arming handle, works the same as a safety switch on a rifle or pistol. When the Loader flips it, he shouts "Up!" to indicate that a live round is in the breech and that the gun is armed and ready to fire.

Outstanding loader!Under 5 seconds is good !

@Zelatur About 7/8's of the casing is cellulose (paper.) It burns away when fired and is blown out of the gun tube. Only the last 1/8 (aft cap) is ejected into the tank turret.

I used to be a Crewman and i don't miss that noise.LOL.I miss everything else.You felt like a badass and invincible.

good consistent loader. he did a good job, including the base deflector lift. :) kudos.

Very simple. When the main gun gets switched on...so does the NBC system, which is designed to overpressureize the interior. Any leaks, bad hatch seals, loose vision blocks or an open breach won't let any gas or liquid in. During an engagement the breach will only be open for seconds anyway, before being sealed with another round. We don't roll with our breaches open. A grenade in the main gun is not a worry. It could disable the firing pin. Also, max depress and it rolls out.

what were you firing at that required sabots? and what all are sabots used to be fired at, other than other armored vehicles?

Can somebody tell me what happen to the expent cartridge? It seems that it was vaporized...

That was fast realoded under 6 second

Hmm... many thanks for the explanations... But the safety arm also restricts/slow downs the loader's rate of loading? since he cannot Down whilst holding a new round?

Yes, you cannot lose the fingers. That's because we use our fists.

What determines what role a given soldier will have inside the tank? Can you join the military with the intention of becoming a gunner? Can you select it? Or do you just sign up for generic tanker training and hope for the best?

what's the lever on the left of the breech for?

What falls out the breech after each round? And why didn't the loader up the gun in the last one just curious?

Damn bad ass 5 sec reload! I bet you can load faster than that too.

@Snakes709 oh i know, when i was doing live fire shoots in the Leo C2, i was amazed at how much a difference there is. We had the pistol port opened and i could hear/feel the other tanks firing, even when i was right beside our gun, as the gunner.

@JoeyDkid does the sound of the hydraulics dont annoy the crew?

Haha, saw that coming. Bound to happen when you got the camera sitting right behind the 900 pound breech block.

Here's a question, I noticed that the loader doesn't always take the safety off and yell "Up!" right after loading a round, what determines when the loader takes the safety off? Does he wait for the TC to tell the gunner his target then take the safety off or is there some other signal to take the main gun off safe?

Is it just me or does the shell casing that drops out look weird? like its cut in half?

I have a question: What's the loud hum the tank makes? I don't know if it's the engine or something else.

What is that constantly noise the tanks does?

is the breech block held up by that little gray latch on the right? it seems like it.

good job dude, nice load time. and good job lifting up on the Avcap deflector. i'd have you as my loader any day. :D

Why is loader seemingly assisting breech block in going up with each reload?

what was that constant siren like drone?

where do the empty shell casings go?

Hey just how heavy is a sabot? Alteast this weight of 2 - 3 bricks?

Respect, you're pretty fast @ reloading.

Soo... Up means closed circuit and Down means open circuit? Also, why doesn't the loader 'Up' immediately after loading and closing the breech? is there a reason?

What's that blue thing on the nose of the round? A sabot?

@TheGreatGizzo If i remember right that sound is the turret hydraulics.Yes we wore helmets that covered your ears and its so noisy that we used communication device connected to each crew members helmet.as far as putting the shell in backwards i don't remember that ever happening.lol.

How much can you endure to maintain your loading speed during real situations lasting for hours? How can you counter fatigue and maintain absolute focus during heavy battle situations? Man vs. Machines, as far as I know humans doesn't do very good.

hmmm really good

It actually made my ears ring!

What's that lever on the left do?

@bossmantyler not as loud as u would think on the inside, outside its alot louder and the concusion hit u

Which is why American tankers are trained to load a round and arm the main gun at a time limit of 7 seconds. Autoloader speeds vary between 3 seconds and 12 seconds, mainly because the turret must be revolved into position to load a round before being brought around on the target lased by the gunner. This can be fatal for a autoloader-equipped tank that has its weapon facing in the opposite direction of where the next shell is to be loaded from.

i played world of tanks.every time i hear UP..it give me goose bumbs.

@soocl0se no, the case is a laminated cardboard type materiel that is burned on firing. Only the stub base is left.

I have a question. Where do the empty shells go?

is the aiming of the tank done by computer or does a spotter have to manually aim and point the gun at a target

Wow. Our hydraulic pump would cut off, once it had built pressure in an M60A2. That continuous whine there would drive me bats.

so by cardboard is it cardboard like a cardboard box or is it a special composite cardboard because the shells look like metal or is it just the silver paint

What is that infernal siren sound?

@DoubleDeePro0duct10ns that's a negative the safe/ arm lever controls on the gunner controls power handles and it's electrical trigger however. if the gunner uses the maual trigger aka" master blaster".. it automatically over rides the safe handle no matter if it's armed or not.

Where do those casings end up?

I just saw today few tanks in a show in el paso texas, including an M1A2 SEP abrams tank... it was my first time that i have seen one in person and i have to say that they are sooo bigger in person than watching videos lol. i was so impresed.

@Snakes709 You feel/hear it a lot more when the tank next to you fires than when you fire.

Wow what a flashback! M1A1 Tankers GO!

Glorious

Good luck. I'll see you here at Benning soon.

@Wadser I guess it does while you are there but 20 years later as soon as I heard that beautiful noise, my eyes watered. I do miss it

Back in the day we used to do that the day before tank table VIII. When I got started you had to check the Crazy "L's" in your conincidence range finder every 5 degrees of temp change so you could get a good range to target. You yougin's these days, with your TTS and lasers....

Was that background noise from the tank itself or was it some siren from outside?

What the hell is that noise! That droning whine sound would drive me insane!

@FrostyBowman thanks that`s makes a lot of sense!

lol please respond how did u sign up for that job like to be in the army and be a tank crew im just wondering for in the future

Is it possible to lose your limb while reloading a tank gun ?

@harlequin2262 Generally, it comes down to rank. The tank commander is always the highest ranking member of the crew. (E6/O1 or above usually) The gunner will typically be an E4-E6. The driver and loader are E4 or below. Driver has the most comfortable position but is also the slowest to get out if there's a problem. Given the choice, I'd probably choose to be a gunner. (the only one that never has to stick his head out of a hatch, lol)

that ever so loud hum in the background is the FCS computer or?

@jonesm16 this is just a gunnery for practice, you can tell, the rounds are blue training rounds

I want your job! That's been my dream for years now.

Do they simply leave the primer stubs on the floor of the tank or does it fall somewhere under the tank

We used to put toliet roll soaked in FRH on the probe of HEAT rounds and fire them down range...soda cans on the SABOT rounds. Guess they don't let you do that any more?

@poonjoo they are combustible, they burn up when the round is fired. all that is left is the metal basplate which is very small and of no worry concerning space

@cubahuba That sound drove me insane just in that 2 minutes of watching the video, lol. Do you have ear protectors that block out that sound? What is that sound exactly, isn't it the engine? Oh and I've always wondered this, has anyone ever put a shell in backwards before?

@JPSwissCheese it drops down when the breach opens.

I used to believe the loader screams "clear"... :(

Sounded like someone was shooting a Bradley outside, heard a 'thump thump thump' that sounded like the Bradley's M242 Bushmaster.

The casings are combustible, meaning they burn along with the "gunpowder" for lack of a better term, that they hold, so only the plate which the firing pin hits is left, im pretty sure al 120mm rounds have moved to these casing, but older tanks still use brass casings.

What happens to the case? It looks a lot shorter when it come out

@bomber6258

3 жыл бұрын

Well it is shorter since the sabot encloses the entire KE penetrator inside (pointy tip sticking out at the very front), so the sides of the round are shot out of the cannon, which then separate from the KE penetrator rod (hence the DS/ Discarding sabot in APFSDS). So only the back end of the round is left in the tank. Heres a diagram: upload.wikimedia.org/wikipedia/commons/thumb/4/4b/TRESPI-5_APFSDS.PNG/350px-TRESPI-5_APFSDS.PNG

true. extra crew is nice.

19 KILO FT KNOX AGONY,MISERY! Thumbs up OSUT.

Hell of alot more quiet then the old m60 diesel engines

Not to shabby. its more fun loading heat rounds in 4.5secs after your adrenaline kicks in lol or switching from heats to sabots and slamming them in 3 secs. I wanna do another gunnery now :(

@skimyy No it is just a base and the primer that are left, no ful case thta is consumed, but unlike the UK system where nothing is left this has the base.

@antonvix an auto loader is just another piece of machinery that can break down, having a crew member load it is much more reliable, yes the rounds are heavy but you only hold them for about 5 seconds, and you wont be loading 50 rounds one after another. All you gotta do is use your man muscles and a little elbow grease. And yes I know from experience I'm an army 19Kilo Tanker.

second round down range knocks the camera off. 7 seconds later loader has another round chambered and another another 3 second and camera is 'up'...good job!

I was a 19K on a M1A1 with C Co 3/8 Cav from 1988 to 1991. I could load a 120mm sabot round in 2.4 seconds. HEAT rounds a little longer, up to 4 seconds.

In actuality, the A2 was designed initially to have an autoloader, but they nixed it in favor of the human loader. In truth, many MBTs with autoloaders can be smaller due to the space needed for a human to operate, however the problem that arises is that, if the machine is out of commission, the prospect of loading is hampered by the machinery that is in the way of the breech.

Well, I am not sure about the Leo, as the Leo2 and Abrams essentially use the same cannon, the 120mm/l44 or L55 by rheinmetall, produced by General Dynamics under license. It is, because both tanks come from the joint development of the MBT70. I always thought, the Leo nowadays uses combustible casing, too. (try the homepage of rheinmetall-defence)

i wonder where they keep all the ammo? and i guess the need to have alot just incase it goes realy bad out there..

@Orca19904

The main gun ammo is stored in a sealed compartment in the rear of the turret and is accessed by the loader through a blast door which he opens to retrieve a round to load into the main gun.

ok, does the actual breech drop down first so the primer stub falls out and then the shell guide drops down second after the loader drops the breech lever?

@Pazuzu6

The breech drops and ejects first, while the arming handle is up the deflector remains up until arming handle is moved down, there is a mechanism from the arming handle to the deflector. It is ver important the arming handle isn't moved down too fast or the deflector will catch the aft cap and cause it so get stuck.

The actual projectile is not that big since it's a fin stabilized armor piercer... But! there's bigger and heavier shell out there... [ KV-2 NOISES ]

That means that you have two men scanning with thermal viewers capable of viewing in x3, x13, x25, x35 and x50 magnification. By contrast, the T-90 does not have two thermal viewers, rather it has a single thermal sight that the TC can override and take control of over the gunner if need be. From what I have read, the autoloader does have a loading time of 4-5 seconds, but you are restricted to only one sector being scanned at any given moment by the single thermal sight.

Gotta love those turbine engines.

@BitnikGr It does matter were the ammo is stored, as well has how its placed. another problem that comes up is tank maintenance. with autoloaders you have more to take care of and one less man to help. now if One crewman is injured your down to a Two man crew to make the repairs, service, and run the tank in combat. the tank would be withdrawn for any of the given reasons. "one less tank on the frontline" and more support personnel needed. you can only make a tank so small!

19K shipping to basic in october. This is badass. Can't wait to get trained on these things.

What variant tho

theirs an m1a2 abrams?

if the gunner misses his first shot, the loader automatically arms the gun. the breech drops when the loader safes the gun if not the breech will remain up

Good luck. If you go Armor, I'll see at Ft. Benning.

@Resendez1959 Thanks for clarifying. It's been a while since I was in a tank.
