The term Weapons applies to many types of weapons used in air, land, and sea applications, and is also frequently misapplied to Ordnance and Munitions. Therefore, this library, as displayed, is all inclusive, but users may choose to delete those products that do not apply to their particular areas of interest. Several optional databases, listed at the bottom of the display, can be selected as cost-effective additions to this library. You may purchase the complete, optimized library, or tailor your library by adding or de-selecting products, as required. To customize your library, simply uncheck the products you do not wish to purchase, or select additional products to further optimize your library. Note that the cost of each library as shown includes a multi-product discount that is based on purchasing all checked items. When you select/de-select products, the discount will be adjusted accordingly.
