class for the items listed. For instance: Grenades, Practice, w/Spotting Charge are (04) 1.2, Mines,
Antipersonnel (Bounding Type) are listed as (08) 1.2, and so on.
Now let's use the class 1.2 tables. Our example is electric primers used with artillery rounds. We
have a NEW of 100 pounds and want to find the following:
The inhabited building distance (IBD)
The public traffic route (PTR) distance
The intraline distance
The above ground magazine distance
The first step is to find the quantity-distance class for artillery primers. Under table 5-21 (fig. 2-21)
we find they are listed as (04) 1.2.
