I'm looking for opinions. I'm getting close to the capping point on my SSU force, and the burning question is: Why get a helicopter? The transports cost as much as a KV suit (any kind), they take up the same support slot as a KV suit, and they're a lot less sturdy - a lot more things can kill them. In addition, at the 300 point level, the board is scarcely large enough to take advantage of their mobility, without risking having them shot up in a trice - 16" may not sound like much range, until you realize that it's about 1/4 of the board in a 300 point game, and it's pretty easy for your opponent to move someone nasty within that 16" range and start shooting you - particularly the American walkers, with their over-abundant machineguns.
So, opinions: What are the advantages of taking a chopper?
