Office of Legislative Counsel
1. During the briefing of Congressman Raid on
10 May I quoted a figure which I recalled roughly
as 25 tons per month for incoming enemy projectiles
in South Vietnam in March and April, but could not
be specific, and promised to send him the figures,
attached.
2. This material comes from the DIA Intelligence
Summary (5 May 1967) and is classified SECRET7NO
FOREIGN DISSEM. Under third agency rules, we can
not authorize Congressman Reid to make further use
of this information, but I feel that the Pentagon
would probably be glad to do so.
3. Congressman Reid also asked for the in-country
strength of the North Vietnamese Army, and the annual
call-up manpower base.

Enem.. Use of Mortars and Rockets
in MUM Vietnam
1. A study by MACV of enemy mortar, artillery
and rocket "incidents" in the first four months of
1967 shows the following increase:
January 44
February 51
March 141 (1 artillery)
April 100 (2 artillery)
The study notes that the reporting is pro-
bably"not all-inclusive, and in particular does not
include all enemy use of mortars as a result of
friendly-initiated actions."
2. Targets for these incidents were U.S., South
Vietnamese, and allied troops, airfields, province
capitals, district towns, villages, and hamlets.
3. The enemy used 120-mm heavy mortars more than
a year ago, but has introduced Soviet 122-mm and 140--mm
and Chinese 102-mm rockets during the first quarter of
1967, also firing 100-m,105-mm, 122-mm and 152-mm
artillery into South Vietnam from positions in or north
of the "Demilitarized" Zone.
4. The pro#ectile for the 140-mm rocket weights
87 pounds, and can be broken down into three components
for carriage by coolie transport.
5. The study gives the following figures, subject
to the same footnote as appended to paragraph 1 above:

North Vietnamese Army Strength
1. In-country strength of the regular North
Vietnamese Army is carried at 358,600 men.
2. This includes 10 infantry divisions, 4
infantry brigades, and 8 independent infantry
regiments, but it is not possible to translate
this into a battalion count (similar to the count
of 91 NVA battalions in South Vietnam) because the
regular or separate regiments do not all have the
standard three battalions at present.
3. In addition to the infantry formations,
there is one artillery division, 1 anti-aircraft
(AAA) division and 80 separate AAA regiments, one
ask armored regiment, and the estimated 25 to 30
SA-2 battalions,
4. There are another 16,500 men in the armed
public security forces (7 regiments and five inde-
pendent battalions), and an estimated 3,000,000
reserves
5. About 110,000 North Vietnamese males
reach the ostensible call-up age of 18 each year;
younger males have been noted among the killed and
captured.
