Hi there,
The easiest way is to use Parenting. Set up one tank as the "Leader", create the animation you want it to follow. Position all the other tanks where you want them to be at the beginning. Select them all and then, in the Parent menu, choose the "Leader tank". The others should now all follow the leader. You can add additional movement to the followers to create a slightly less regimented feel if necessary.
Hope this helps!
cheers,
Angie
