Guns/Howitzers: Acc 0.9 Rel 0.9
MRLs: Acc 0.6 Rel 0.8
Mortars: Acc 0.6 Rel 0.95
ATGMs: Acc 0.6 Rel 0.7 GE 2.0

Can you tell me what the Acc/Rel mods. are
for RPG/LAW, and for Automatic Cannon?

Weapon Type Estimated Accuracy
Small Arms 0.85
Automatic Weapons 0.70
Mortars 0.75
Rockets (unguided) 0.50
Bombs (unguided) 0.40
Standard Rifeld Artillery Weapons 0.85
Standard Smootbore Weapons 0.60
High Velocity Guns 0.90

Special rules are applied to the calculation of ATGM OLIs with respect to: accuracy, and additional factors

(1) The following factors relating accuracy to guidance are used for ATGMs

Wire guidance (daylight only) 0.80
Wire guidance (day or night) 0.85
Standard radio command 0.85
Radar Beam 0.90
Laser Beam 0.95

(2) Additional factors applied to calculation of ATGM OLIs are:

(a) Minimum range factor (MRN). Standard minimum distance before arming is is assumed to be 100 meters

MRN = 1 - [.19MinRnge - 100)/100]

Exmaples: TOW min range is 65m; MRN = 1 - .1(65 - 100)/100 = 1.035

MILAN min range is 300m; MRN = 1 - .1(300 - 100)/100 = .98

(b) Penetration factor (PEN). Standard penetration is assumed to be 500mm

PEN = 1 + [.01 x SQR(penetration - 500)]

Examples: TOW-2 penetration is 800mm; PEN = 1 + (.01 x SQR 300) = 1.17

HOT-2 penetration is 1300mm; PEN = 1 + (.01 x SQR 800) = 1.28

AT-7 penetration is 400mm; PEN = 1 + (.01 x SQR - 100) = 0.90.

(c) Velocity factor (VEL). Standard velocity is assumed to be 400 m/s. VEL = 1 + [.001(velocity - 400)]

Examples: HVM velocity is 1500 m/s; VEL = 1 + (.001 x 1100) = 2.1

DRAGON velocuty = 100 m/s; VEL = 1 + (.001 x 300) = 0.7

HELLFIRE velocity = 500 m/s; VEL = 1 + (.001 x 100) = 1.1

(d) Enhancement factor (EN). Total value cannot exceed 1.4

There are two kinds of enhancement:

- Accuracy enhancement (ENa): IF CEP is less than standrad ENa is >1.0 and <1.3. If ph is above standard ENa is >1.0 and <1.3
- Other enhancement (ENo). Currently applies only to ability to track through obscurants, or other countermeasures. Value is judgemental, betwen 1.0 and 1.3.

(3) Reliability (R) is defend as the average number of strikes which result form a large number of tries. Reliability is an expression of the probablility of a strike given a try Weapons do not always work as intended. Some tries do not result in a strike because the wepaon misfires, jams, or otherwsie malfunctons. If the proving ground reliability is not known, a value may be assigned based on judgement. Samll arms should be assigned a reliability of 1.00 if a specific value is not known.

1) Publish a revised issue of NPW that uses the TNDM.

2) Make our user's guides and manual publically availible.

3) Sell the computerized program for a price the hobbyist could afford.

I am still leary of such an effort, as I do not think there is a lot of real money in comerical wargaming. There certianly is in "Doom" and other such games, but not in real wargames. I do note that people like Mark Hermann and Larry Bond have not given up their day jobs.
