For information, I have never seen an operational VAB Genie with a dozer blade mounted.
In the version used by the French army, the only difference with the regular infantry variant is that it is rigged to carry
a set of engineering equipement (towing cables and counterweights, anchoring poles and spades, the works).
In most pictures (
e.g. here) you won't even find attachments for a blade on the front hull.
The only VAB with a blade regularly attached in front is the
VBMO internal security version (sorry, no english version), which isn't used by the Army.
The only non-Gendarmerie version I have found with a blade is
the Air Force airbase security VIB with 20mm, apparently used to clean up airstrips after attacks. There is now unit #574 in OOB 06 classified as gun APC.
To get to the point, I'm not sure the VAB Genie with blade is too realistic as engineering tank, and too relevant to the game as an APC.
