Possible to set units on HOLD at scenario start ?

[TheBigRedOne]

A very simple workaround could be the use of a new optional rule.
"Hold fire on first turn"

This rule would only affect the defending side (AI or Human) and dont allow any opportunity fire from defending side units during the first turn of the attacker. Should be quiet easy to include.

It's probably not as easy as it sounds, given that it's altering the coding. If it happens, it won't be until a new title is in the works, which is when most engine changes occur.
