In a tank, it seems to slow down and catch on fire which will slowly "bleed" the tank. Is that all?

  1. Does this happen right at 50%?
  2. Does repairing above 50% relieve the affects?
  3. Are the affects the same for all vehicles?

It can definitely be frustrating to disable an air vehicle, yet watch it fly away and recover!

  • As an FYI, I experienced a situation where I repaired a vehicle to 72%, but it was still "disabled" and moving slowly. Maybe there is a bug with the repair system right now.

I just investigated your question on my server (standard - not hardcore in case it matters) with a couple of M1 Abrams tanks. I haven't confirmed these numbers for other vehicles, so results might be different for other vehicles.

The magic number

The number for disabling looked like 50%. I would have guessed it was that, but I'd never tested to be sure. A 52% tank was fine, and a 50% tank was on fire.

Bleed effects

Once the tank was disabled, I had a grace period of a few seconds before health started bleeding. It seemed like about a 10 second period.

But 50% was the point where it started bleeding. Once it starts bleeding you have to either get it repaired or, failing that, bail out before it explodes.

Audio cues

  1. Down to about 60% damage I heard a slow klaxon-like sound (like an angry little alarm clock).
  2. From 50-60% the klaxon got very fast.
  3. At 50% and below, once the vehicle was on fire, the "woop-woop" alarm sound was added.

Heal effects

When a you repair a vehicle's health to the point that it's no longer disabled, all adverse effects from disabling are repaired too.

When a vehicle is anywhere above a disabled state, after avoiding additional damage for a few seconds it'll slowly regenerate its health back up to 100%. In my tank testing it took about 12 seconds of non-damage before regeneration started.


Though a disabled vehicle's movement is impaired, its weapons function normally.

    note that regen requires the "repair" perk to be equipped. This confuses a lot of folks because it's the default perk on tanks. But that's not always so as you unlock additional perks.. and repair must be unlocked, for example, on the IFV and AA vehicles. Nov 12, 2011 at 9:43
  • @JeffAtwood +1 for enlightening me about the default perk!

    Update: sometimes a vehicle will be above 50% damage but still on fire and gradually losing health. While not directly relevant to the question (it's not about disabled vehicles), I wanted to clarify that not every flaming vehicle is under 50% health. Nov 15, 2011 at 23:11

    According to here, this answer is incorrect in two respects: The disable-point is not at 50% for all vehicles, and the vehicle remains disabled until it is fully repaired to 100%. Feb 23, 2012 at 17:56
  • @BlueRaja-DannyPflughoeft, thanks for the link. I tried to be clear that I'd only tested on one vehicle type, but I've added the disclaimer now that results may vary by vehicle. As for vehicles remaining disabled until they get to 100%, I'm almost certain that wasn't true when I tested (I'm unable to test currently), but maybe something changed in a patch. The EA help site also says vehicles will only repair 25% on their own, but that was definitely not true when I tested: vehicles at 52% went back to 100% without any help. So either a patched changed things... or EA support is wrong. :-) Feb 23, 2012 at 22:04

When a vehicle has been disabled it will have its moving severely impaired. You can control some parts, but it will move slowly and you're basically a sitting duck (or in the case of airborne vehicles, a falling one :)

The only way to get a vehicle back from a disabled state is to have a friendly engineer repair it, or - for airborne vehicles - by using the "Extinguisher" vehicle upgrade that will put out the fire on disabled crafts. This is probably what you have been experienced when you saw an air vehicle fly away after being disabled.

I could not find any reliable sources on what exact percentage that causes the vehicle to enter the disabled state (or the "on fire" state), but the battlefield wikia suggests it's movement start to degrade around 50% and catch on fire around 20% Typically, for airborne vehicles, one hit with a stinger will disable it, leaving it plummeting to the ground unless it's fire is extinguished or an engineer inside it repairs it.

Also, as you've noticed, a vehicle on fire will "bleed" in that it will slowly do damage over time until it explodes.

  • I think I've seen a vehicle on fire in the 40's...

  • Yeah I'm also under the impression that disabled and on fire are pretty close (or the same) but I don't have any evidence. Drew B's answer indicates "disabled" automatically leads to the fire/bleeding after a few seconds

I can only answer #2 from personal experience. I've been able to repair any land vehicle down as low as 10% all the way to 100% with no after effects. My opinion is you're correct on #1 but I can't verify.

As far as disabling an air vehicle and it recovering, you can repair them in the air from the non-pilot seats. If they had more than one person on it, it'd be a pretty quick repair, able to be done before crashing if they are high enough.
