You see, under the old wars, the would have just taken the penalty and looked to have Mick Dundee go aboard and commandeer the vessel for themselves. Predictable, but safe.
Now, under the EWVs (those are "Experimental War Variations" kids!), they can use these exciting new torpedoes to blow the opposition to kingdom come! While the main focus may be back in the safe part of play for the longer period of time, those fast charges upfield (thanks to the superior fitness required for EWVs) are bound to literally rip through the defenses armor!
The main benefit of the EWVs though is the increased safety for the grunts of war. With less physical contact, there is less chance of neck or back injuries. However, now that the final mauling of the enemy can be brought down with a tactical strike to the front ranks, the risk is a risk in itself.
