Four Points eh...
Well if their the standard Toad... Jumping is standard movement, just leapfrog from shelter to shelter, staying next to buildings or level 1's as much as possible, only walk ( technically this is called jogging for Infantry ) if you have to, mostly underwater ( 1 hex a turn ).
But if you can get some transpo, better protect it, ride not die! ALWAYS deploy away from the fight, but as close as you can, behind a level 1 or higher or behind a treeline if possible.
