Have playtested the Insertion scenario several times now and ironed out the bugs.
We have found it works best as a 1500 points battle (any more and the attacking force gets swamped in the first turn any less and there arent enough attackers to actualy last through the 6 deployment turns).
The defender has no Heavy Support, Fast Attack or vehicles with a total armour value of 33 or greater but they get an extra 250 points to be spent on Troops and all Troops choices gain the sustained assault special rule. The attacker has 1500 points, no Heavy Support and only vehicles that can deep strike and have an armour value less than 33.

Appart from these changes play the scenario as mentioned in the initial post.
