So, reading the below provided cut&paste from the rule book - and taking the 'literal' meaning of the written words, I see nothing wrong with doing the following on my large vehicle deployment activation. ~Deploy large unit in the first open square, leaving the rear 'out of play', then ending my turn. This would prevent any enemy from targeting my vehicle until I brought it fully onto the map, which I could do on round 2 with a move action, and still attack in that same turn.
Now I read it over a few times, and yes - it does say that the player Must Make a Second Movement Action to enter the board, but it does not say that I need to take a second action at all...meaning, If I opt to take a second action, it must be a move, but there is nothing saying I Must make a second action. What it does say is that IF I intend to fully enter the battle, I must make two move actions.
"Because of their size, some large vehicles cannot fully enter the battlefield with a single move action. These units
must perform a second MOVE action to enter the battlefield."
Now, the above text in the rule does NOT say - These units must perform a seconds MOVE action AND enter the battlefield.
Your thoughts??? I think it would be a very interesting strategy.
-----Actual Rule Text Below -----
Entering the Battle field
Like any other unit, large vehicles must use a MOVE action to enter the battlefield.
Until they are completely on the battlefield, large vehicles cannot perform any actions other
than the MOVE action, and cannot be targeted by an attack.
Because of their size, some large vehicles cannot fully enter the battlefield with a single move action. These units
must perform a second MOVE action to enter the battlefield.
Example: During the first round, a Königsluther is entering the battlefield. Its
first action for the round must be a MOVE, which puts both of its front legs on the
board (diagram A). But that’s not enough for the walker to be “in play.” So, the Axis
player must perform a second move action (diagram B) for the Königsluther to fully
enter the battlefield (MOVE + MOVE).
To enter the board, the Königsluther had to spend both of its actions, so it must wait
until its next activation to perform more actions. Now that it is fully on the board, the
Königsluther can be targeted by enemy units.
