Due to input from local commanders, the UNE technicians developed what would come to be known as the "mini-plas". While using the same technology as the plasma grenade, the mini-plas creates a wash of plasma over its 3" burst radius rather than distinct fragments. The downside is that the weapon only causes superficial damage to vehicular targets and heavily armoured powered infantry. The upside is that it is far more effective at neutralizing lightly armoured powered infantry as well as non-powered infantry.
The mini-plas is identical to the plasma grenade but uses general modifers and gets a +2 modifier against NPI and a -2 modifier against LV targets.
The UPV change is negligible (about -3 points for each fig that take up this option under current rules but that would change with the release of Stormfront).
Is that an acceptable fix, sergeant_hastp?
