Cooooooooooooooooooooooooooooooooooooool but I was thinking on something like this:
*Ingame*
<Icon> Bayonet Charge
Orders the Japanese Soldier to attack nearby enemies with it's bayonet. The caster will automatically select the nearest enemy organic unit and instantly rushing onto it, in a suicidal however powerful meele strike. In this mode, the Japanese Soldier is much more weak, however fast and hard to hit.
*Ingame*
Well I don't understand that much of triggers, but the effect is to make the selected units to rush into the nearest enemy organic unit. To avoid problems, the spell would buff the targeted unit with a dummy buff. Units with that dummy buff cannot be targeted again by other soldier, unless it is removed. If the caster dies before the attack, the attacked unit will obviously be debuffed and will be targetable again by Japanese Infantry. There is, however, two problems:
1st: I don't know if that is possible.
2nd: The fact that the infantry is equipped with SMGs, and it wasn't common to have bayonets in your SMG, only in rifles.
An alternate way is to change that spell to melee attack. In the case of normal infantry, they would attack with they SMGs by punching their enemies with the weapon's stock. In case of engineers(if they use rifles), they would charge with bayonets. In the case of machinegunners, they would leave the MG behind and take a Katana(that ninja sword) and run to the target, or, if they use a Type-99 LMG, they would attack with bayonets.
