Effects

Say there's a Chinese copy of a PT-76 charging at the gate of your Special Forces outpost.

You've managed to find someone who remembered where the HEAT rounds for the M67 recoilless rifle were kept in time to fire them.

The thick armor is the front of the turret.  15mm RHAE.

That's DR 41.

The average hit from the M371A1's 6dx3(10) does 63 points of raw damage, but divides the armor by 10, so only 4 points is stopped by it.  59 will penetrate.

The reckless rifle will definitely put a hurt on a PT-76.

So will an M72 LAWS.  It does the same damage.  It's a LOT lighter, just 5.2 lb.

Of course, a LAWS can't bring the hate of the canister round...

With a skill of 11 at a range of 50 yards...

 +4 for aiming.  +1 for bracing.  +1 for the optic.  +11 for rapid fire.

-8 for range.

Chance to hit is 20.

Average roll of 10, hits by 10 so 11 flechettes will hit.

2d cutting each, average hit of 7 points, 10 after penetrating the VC's uniform...  110 damage on a HP 10 person is well past the unresurrectable auto-death.  Pink mist territory.

Oh, and it's a cone, so his buddies get to share in the fun.
