My question is simple and pretty much in the topic - Corsair Wasps have the Jump Pack that allows them either an 8"-12" teleport during Movement at the cost of getting onto snap shots, or a highest 2-of-3D6 charge and bonus to HoW when used in Assault. If it uses either, the Wasp gets a rerollable 4++ until the next turn.
It's possible to abuse that by declaring a charge, using the Jump Pack, then using Fleet to reroll dice to make sure you don't make the charge and are a nice rerollable-4++ toting gun platform the next turn at the cost of eating some Overwatch. However, can you declare that you're using the Jump Pack during assault, but then not actually assault? This would give the rerollable 4++ without having to suffer overwatch, as well as allow you to use it after Scouting, out of Reserve, or in other situations in which you're not allowed to charge.
The text in IA11 is, "A Wasp jump pack can be used in either the Movement phase or Assault phase... If used in the Assault phase, the Wasp Assault Walker may roll an additional dice when determining Charge distances and use the two highest results, and additionally gains the Hammer of Wrath special rule for that phase, inflicting D6+1 hits instead of just one."
Seems to me that allows you to declare use of the pack without charging, though that's something I'd appreciate a second opinion on. And just as a side note - would Immobilization prevent the Wasp from using its Jump Pack too, or would that just cripple the "leg" parts of it?
Seems to me like a 70-pt Wasp toting a pair of Scatterlasers with a rerollable 4++ save that can also assault in a pinch wouldn't be an unwelcome addition to a force that includes Corsairs.
