SEP lead


Recommended Posts

There is a problem with the M1A2 SEP lead. When targets are moving slow towards your tank at an angle, you track and engage. The round is landing as if there is no lead applied. The lead is suppose to be updating every .03 seconds. This video demonstrates the lead failure:https://www.dropbox.com/s/jnsnkflymo8kuh7/SBProPE64cm_2014_10_16_17_03_48_791.avi?dl=0

I noticed this with ranges beyond 3800m and chalked it up to being out of the seat too long, but after a few more experiments, I think you're right; lead may be broke at long range. Could it be that lead isn't being accurately calculated beyond 4000m for the SEP?

Lead only updates once vehicle is lased, so if you have a good range and don't shoot right away you will need to relase the target to update lead.

Thanks

Negative, it updates after a lase and continues to depending on the movement of the gunner or tank commanders control handle azimuth movements. If the handle movement stops lead is then set to zero. The range of the target needs to be updated in the ballistic solution. That's why you relase.

The issue isn't range, it's the angular velocity of the turret. Switch to the GAS after lasing and you'll see that it appears to have a threshold below which it doesn't apply any lead. The M1A1 works fine in the same situation.

The lead is working correctly in this video.the issue was lead with the m1a2 to start with

Good find! It seems to be caused by the feature of the M1A2 that cancels lead if the gunner centers his controls.. and it seems these slow-moving targets do not require sufficient control input to 'escape' that 'controls are centered' zone.. hmm
