I take that on "less desireable" for the rounds. But why then bomb whole villages, like in Afghanistan? I am not bickering. . . only thinking. That does not make sense. In urban combat, civilian will never do good. And the slugs will go through one wall, with killing power, not through several walls.
In the nowadays Bundeswehr a "drill-sergeant" told me, that when the enemy is in cover (a building, for example), put up the MG3 and make some thousand holes in it. Later go a see what is left over.
To angel: I will quit making remarks, that could be read as political. . . I am a Brit, but I have a brain. I never understood why it is wise to omit politics and religion in talk. . . untill I came over and saw it for myself. So, althrough this board is British, not US-american (you are guests here), I will make this consession for my US-american friends.
For the grenades: As I understood it, the Land Warrior grenades would count spins, to get the distance to go off. The grenades were to small. But why combine a grenade launcher with an assault rifle in this way?
Why not use much bigger grenades, say 60 or 70mm, from a squad operated launcher. Use two lasers of differnt wave, and give the grenade a simple reciever for both. One laser would be on the launcher sight, the other in the squad (sergeants or corporals gun sight). Both lasers have to converge on the target (behind and above cover), which needs a certain angle between laser one and laser two. According to wavelength one or two meters between the lasers would be enough.
Fire the grenade. It will be set off right on target, where the lasers converge, as the second laser user (sergeant or corporal) wishes. The launcher could maybe fire several differnt muntions, also anti-tank.
This is an old german bombing method (knickebein), which used not laser but radio signals for night bombing. Sturmgeschütze (Stug) used a similar method, without laser or radio, with "Abpraller", bouncing off grenades, to get airbursts over troops in cover.
