Seeing as they're talking about older vehicles, specifically Merkava 2's & 3's, I doubt Namers would be on the cards. However, that still leaves the possibility of Israeli upgraded M113s, Achzarits, NagmaSho'ts & Nakpadons (with US agreement).
Interestingly, this leaves open the question of what has happened to the Israeli Ofek APC conversion program (based on Merkava 2 & 3 hulls).
