A thought on Mech

As we all know, 5th edition has revolved around mechanised troops choices.  The armies who are better at this are coincidentally those armies which are stronger than others. 
The traditional view is that you place your troops choice in the transport and it protects them from enemy fire, and hopefully gets all the way over to the objective before it is destroyed, although in an ideal world, it won't get destroyed at all.

The normal way to achieve this would be to deploy a lot of transports, to ensure at least some of them make it across the table, but it can still cause you problems if they blow up too early.

One of the things you can do to increase the survivability of your transports is to spend a turn out of the transport, when the enemy small arms weapons are not in range.  The idea of this is to try to make your opponent fire his heavy weapons at the troops.  Now this might seem a stupid idea, but let me elaborate. 

You could have 3 rhinos and three razorbacks, transporting various marines.  What I am suggesting is to deploy one unit outside of their transport, or disembark onto an objective early on in the game.  The idea is that the enemy will target the troops unit, and shoot them in preference to the rhino.  If all goes to plan, you won't loose the entire unit of marines, but they will absorb a significant amount of enemy long range fire.  Don't do this within rapid fire range, or it could go badly wrong.  Once you have taken a turns worth of fire, hide them back inside the rhino which has been spared a round of shooting.

What you are trying to do is control where the enemy concentrates their fire.  He needs to beleive you have made a mistake and thus the unit draws a lot of enemy fire.  However as long as one model survives, to get back inside his rhino, the unit is still scoring and you haven't actually lost anything!
