1. 90mm projectile, anti-armor HE Squash-Head shell. Intended to blow the interior of an armor plate loose as killing fragments without necessarily penetrating the armor directly.
2. HE/FRAG/MOVE/EMR/STATIC/FIRE/LUCKY/JET.
3. Unexpended shell from a M691A2 HESH round. Fired by 90mm cannon. Not sure when this round was introduced, or when (or if) it was retired. Lots of things have fired 90 mm over the years, back (at least) as far as the M1 Anti-aircraft Gun in WW2. The M48A3 tank, Light Armored Vehicle-Assault Gun (LAV-AG), M67 90-mm recoilless rifle, and M56 Scorpion self-propelled Antitank Gun all used 90 mm.
4. Impact or graze fuze. Have not found an part number.
5. I can google links to FMs for EOD, but they all require more than my email-only AKO. So I'm stuck with "set C4 next to it" and "shoot from a distance to trigger the impact fuze."

Good Job Pinhead - Man the Civilian getting this again.
In gerenal this rocket is fire from Mult-Barrel Rocket Launcher (MBRL) and most have 12 Tubes that are in rows of 3-4 tube "sets".
Type by Function: Chinese RKT, 107MM, HE-FRAG (TNT)
Safety: Ejection, EMR, FRAG, HE, PROX, STATIC
Fuze: Typically these have a PD, Type 3 Fuze, they can have a ceremic Fuze that is MP1(A). No LUCKY/JET with this UXO. But its better safe than sorry.
Attack (Disposal): Warhead with C4, some say counter-force.
Okay if the "ammunition" used with the MBRL is the Rocket which consists of one piece a warhead is attached to the rocket motor and has a fixed amount of propellant is contained in the rocket motor.
What additional do you need to worry about while disposing this UXO with this precaution above?
