VBS3Fires v3.6.3 User Guide

VBS3 mission editor, and open the Fires Battery object that corresponds to the guns you are

concerned about. Check their actual error values and ensure they are sensible. For muzzle

velocity they should be 0.1 or less. For elevation and orientation they should be 0.3 or less.

2. If you are using grid coordinates, ensure that you are entering a grid reference and that you

are using the correct coordinates system.

3. If you are using polar coordinates, ensure that you have provided an accurate update of the

FO’s current position.

4. Because all rounds follow a ballistics trajectory, the effect of the ground and terrain contours

may affect your fall of shot. This accurately reflects what happens in the real world, but may

be the cause of the confusion here.

28.3.1.2 My guns will not fire at all

1. The most common reason for this is that the target is out of range for those guns. Check

your radio log and you may see a message from the Battery stating that they cannot engage

that target. You will need to move the Battery in order for them to engage this target.

2. It is possible that your radio messages are not being received by the Battery that you believe

you are sending them to. If you use a callsign that is not used by this Battery, they will ignore

the radio transmission. Check your radio log, if you are receiving replies to your radio

transmission then you know your signals are getting through, otherwise check that no

firewall is blocking transmission on the VBS3Fires ports. If this doesn’t work contact the

support email address.

3. It is possible that your guns are out of ammunition. Check that you have given the guns the

correct ammunition in the VBS3 editor, and that you have not already fired that many

rounds during the scenario.

28.3.1.3 When I try and fire the guns, I get a ‘Target too close’ or ‘Target too far’

response over the radio.

1. All guns have a realistic and configurable firing table which determines the muzzle velocities

for the guns. Based on these firing tables, VBS3Fires calculates a minimum and maximum

range for indirect fire from each gun. If the gun is instructed to fire at a target which is too

close or too far, it will send the corresponding message over the radio. The only way to

correct this is to move the guns, fire a different target, or to change the charge tables.
