Specifying gun-line parameters

The VBS2Fires Gun-line object parameters are:

1. Gun-line name. This is the name that will be displayed inside VBS2Combined Arms to represent that gun-line. It must contain no spaces or punctuation.
2. Doctrine.  Specify to use the US or Commonwealth call for fire doctrine for this gun-line.
3. Callsign. This is the Callsign for this gun-line. It must match one of the entries in the radio net for this mission. It cannot be left blank.
4. Calibre. This specifies the calibre of the guns that are firing.
5. Gun type. This is a drop down box from which the user can select a template gun type for this fire asset. As the user selects different options from this list, all of the options below will change accordingly. Any of those values may then be modified individually in order to customise this gun-line.
6. Estimated errors. All guns can have estimated errors in the muzzle velocity, orientation, and elevation of the guns. Each of these errors is a Normal distribution (bell shape curve), and the values here allow the standard deviation of those curves to be specified. The individual errors are:
   1. Muzzle velocity. This is the percentage of variation in the muzzle velocity of a round that is fired. For example, a value of 0.01 would mean a 1% variation in the muzzle velocity. High values of error here will result in wildly erratic falls of shot.
   2. Orientation error. This is the number of mils to which the gun is likely to vary left or right between shots. Note, unlike muzzle velocity, it is an absolute number of mils, not a percentage.
   3. Elevation error. This is the number of mils to which the gun is likely to vary up or down between shots. Like orientation error, it is an absolute number of mils, not a percentage.
7. Actual errors. The errors specified above are the estimated errors and are used to calculate probable error by the fire control computer. In contrast, the actual errors will result in actual deviations in fall of shot. Estimated and actual errors are separated so that the user may simulate a belief that the guns are more accurate than they actually are, or vice versa. The individual components of the actual error are the same as described above.
8. Number of rounds. Here the user can specify the initial number of rounds of each type for each of the guns in this gun-line.
9. Record Target Prefix. The target name for each gunline starts with this prefix. Targets which are recorded without specific names are recorded with this prefix. Using the same prefix for two or more gunlines will create confusion in recording targets. Therefore it is advisable that separate prefixes be used for different gunlines.
