ITEM is a suite of terminal effectiveness models that provides a user-friendly PC based environment and toolbox for undertaking assessment studies.  It combines comprehensive analyses of the physical interactions in the attack, and of the resulting damage, with the latest GUI and graphics facilities for results analysis.
ITEM has several main elements:

• Input – A library of pre-defined targets, weapons and engagements, plus facilities for analyzing and reviewing the associated data.  Tools for modifying existing items or creating and checking new items.
• Assessment – Tools for the assessment of lethality/vulnerability, including IFWAM (fragmenting warheads), KEWAM (KE penetrators), ATLAS (Anti-armour:Shaped charges and explosively formed penetrators), HELHOLE (large interceptors), plus the INTAVAL program suite.
• Output – A library of all the results from previously run assessments, with direct access to the corresponding input data.  Formats include tabulated data, Excel spreadsheets and graphics.  Visualisation of the engagement includes trajectories, target damage and the ability to create animations.
• Main GUI – The main GUI provides an overall interface into which all the other aspects are fully integrated.
