[quote=@Durandal] Wouldn't said coil gun mortar still need to be quite large? And the purpose of the rail gun isn't to defeat tanks but light armored vehicles. The cumbersome nature is also a reason why it rarely sees use outside of defensive positions due to the time required to set up the gun. [/quote]Well, it needs an energy source (which would likely look like a car battery in size/weight), the launch tube/system (kinda the same weight as a larger ATGM nowadays), some kind of pod to provide stability and of course the warheads. It'd be a two-man system alright but it won't be particularly that bad in regards of weight. Like I said it'd be like a somewhat heavier mortar system. Actually, there are plans to make mortars launch their projectiles via coilgun mechanisms. Each of your projectiles would only have half the weight compared to missiles with similar role, so about 10-15kg a piece. The weight of the Mortar could be reduced by CNT or other carbon-polymers, although I think it might be counterproductive at one point due to the recoil. So perhaps 50-100kg for the weapon system alone. Let's surmize. 10-15 kg per warhead, let's say they carry 3-4. 15kg for the battery 60 kg for the weapon itself. Unless the two are already encumbered this set-up is viable for a two man team.
