    throw a parachute on it so it’s aligned vertically, make it detonate when it lands, make it blow straight down as opposed to all over the place, and try to get that thing to land on a tank

    You’ve basically just described a HEAT round without the melted copper penetrator.

      Actually, they just described a HEAT grenade. Of the cute anti-armor grenades with parachutes, the RKG-3 is a great example. The purpose of the parachute is to make sure the HEAT penetrator is facing the right direction.

      I was thinking more of the tried and true soviet RKG3 and the half dozen variants/clones. They’re terrifying when they work, but everyone figured out that cope cages and improvised shields create such a gap that renders them mostly useless, and at the end of the day it’s playing lawn darts with a tank. For some reason they’re still all over the place, probably used more for IEDs or destroying infrastructure than tanks

        Not sure how much I really want to commit to that air gap idea. Pretty much every time there is data, the ideal standoff is somewhere between 8 and 12 times the diameter for a given HEAT warhead.

        The nets and cages seen like on US vehicles weren’t designed to give standoff on an ideal detonation, but to catch the nose of an incoming round in the open space and hopefully strip apart or dud it. It is commonly called “statistical armor” because it relies on the statistical chance of being hit in the right place to work.

        MPDI link article with charts and more explanation.

        Against a weapon which won’t be shorted out by this armor it is, well, cope. The reason you don’t see RKG-3s often in Ukraine footage is more likely they they aren’t common, and other better options that can be fired accurately and from more distance are.

        HEAT is just a type of warhead. You can put it into lots of things. You are correct that the front of the warhead needs to be facing the target.

        In hand grenades, the penetrator usually faces down compared to the “stick”. The sticks in these grenades are not simple wooden sticks, but hollow metal ones containing parachutes. The grenade is meant to be thrown in a large arc or dropped from above (from a bridge or building) on to the tank. The parachute helps drag the back of the grenade and keep the penetrator pointed at the target (maybe).
