That. Would be something I'd appreciate a lot for the Rifle Grenades here.

Maybe tone down the smoke trail just a bit for this mod, but aside from that, it's perfect! Explode on impact, good amount of inaccuracy, and it just looks cool.
By the way, would it be possible to get the soldier to aim up when firing it? Doesn't look like it in the video. Just purely visual, btw.
You can use this as introduced in the unused javelin.weapon:
Code:
<ballistics near_far_distance="1.0" speed_estimation_near="20.0" speed_estimation_far="35.0" max_speed="100.0" randomness="0.07" />
That low near_far_distance will make the shooting practically always use the "far" mode, thus using speed_estimation_far as the speed for the projectile. The "javelin" will shoot it almost upwards but using lower speed would get the arc more lower and visible.
The smoke trail is coming from the projectile, so you'd stumble on stuff like:
Code:
<effect class="activated" ref="Propulsion" />
Just remove it to get rid of it.
I think the animation for shooting would work also with slightly upwards tilt, but it needs to be at least a bit pointed forward in my experience, otherwise the weapon will refuse to shoot.
