SIM DISTRIBUTION
1. The introduction of rockets into the Viet Cong/North Vietnamese Army(VC/NVA) arsenal in the Republic of Vietnam has presented us with adefinite challenge. We are tasked with developing countermeasures which Iwill stop the rocket threat or make it ineffective.
2. Much has been learned and written about the eneLV rockets and of theiremployment by the VC/NVA. One vital aspect, however, still remains un-solved: how to detect and destroy these rockets prior to the time of attack.
3. This study provides background and the latest informition availablean VC/NVA rockets. It is anticipated that this information will assistour efforts to meet the enemy's challenge.

INRMODUCTION
The primary purpose of this etudy is to familiarize personnel with enemy
rocketry, its method of employment, capabilities and characteristics.
Specifically, this study is intended for personnel who normally do not
have ready access to filed information concerning enemy rockets. Through
knowledge of the enemy rocket threat, units can more effectively detect
launch areas and prevent rocket firings within III Corps Tactical Zone.
Much of the information contained in this publication has been extracted
frvm the many reports and studies that have been made on this subject.

CH AMERISTICS OF THE 107K ROCKM
The CHICC) 107ma rocket, H-12 (figure 1), is a spin-stabilized, barrage
rocket possessing a high explosive fragmentation warhead. It is employed
in the Republic of Vietnam (RVN) as an artillery barrage rocket against
point and area targets. The 107=. is basically an improved version of
the CHICOM 102m rocket.
The rocket consists of five major cospcnents:
1. A point detonating fuze
2. A high explosive fragmentation warhead
3. A warhead-to-notor adapter
4. A rocket motor
5. A Ventri motor plate with six canted noszles which producu a
clockwise spin,
The 107. rocket 'mploys the CHICCK type 1 fuse, which is essentially a
copy of the V-25 faeo. This fuse has superquick and delay settings and
is armed by centrifugal force. The rocket is launched electrically from
a manufactured launcher or any one of several improvised launchers, i.e.,
mounds of dirt and cross sticks (see Chapter IV). The rocket can be
launched in approximately three minutes from a remote position, using
40 meters of electrical wire or a delayed firing device capable of up to
