Michael, in some old patch the following rule has been introduced:
The new rule says: "50. Gameplay Change: Change to river assault – reversion to original rule - when crossing a river into a hex all units entering should shock attack in the turn they cross, unless 1/3 of the unmodified AV of the defenders has already crossed from that hex side in a previous turn."
I have posted to an old thread but kindly ask for your comments here too.
This turn (p8) I've got an assault triggered by a division sent to aid the defense E of Sibolga.
Japanese Shock attack
Attacking force Assault Value = 652
Defending force Assault Value = 1752
Japanese adjusted assault: 0
Allied adjusted defense: 3490
Japanese assault odds: 1 to 99
True, there may be not enough troops to met the 1/3 AV rule (although the 652 vs 1752 AV seems ok).
I'm perfectly ok with shock attacks when crossing the river without enough AV.
But maybe, just maybe, a shock attack
should not be triggered regardless of who own the hex?
I owned the hex. I own it for months! Not from
the previous turn.
Why the crossing trigger shock attack if the hex is mine?
Based on (my)

simple logic, IMHO its seems a bit weird that the forces crossing into friendly hex well secured for months suffer such terrible losses. I think that if I own the hex, I've got total control of the place and the crossing is secured.
Creating bridgeheads and getting into an enemy occupied hex is one thing, normal troops movement in secured hex is something different. Should it trigger the shock attack if my troops are simply moving on a bridge to fill the
long owned trench line somewhere 40 miles away?
Some losses from long range enemy bombardment attack ok, but a shock attack and annihilation of a whole division? [&:]
If in your view hex control doesn't matter during river crossing, maybe there should be some check of who owns
more hexsides of the contested hex? (in metaphore -- who has more land secured, check if the forces there are not encircled etc.; like 0 - 2 shock attack, 3 bombardment attack, 4 - 6 no punishing attack at all)?
