Wiped out passengers

[Jumbo]

It's quite apparent in the game that if trucks/halftrack or tanks are attacked by either direct or indirect fire while carrying/transporting troops. those troops/passengers being transported by those truck/halftracks or tanks are very easily wiped out. It is realistic that those transported troops would suffer greater, And even far greater losses than troops moving about in the open under most conditions. However my question is this. Wouldn't those troops being transported dismount that or those vehicals once they came under the kind fire that would wipe them out ?. My thought it to have it programed in the game, That if a vehical did come under direct or indirect fire that was transporting troops. Those troops would be forced to dismount provided it would not over stack that given hex they would be in. If that hex would be over stacked with SP's, Then those transported troops would suffer those terrible blows that they have all ways recieved in the past. Any ideas on this ?
