Cheers isuzutoo-eh and the kind front-desk lady. The 44 is the bridge class of the tank much the same as the yellow disk on some of your lands out there. In tank world, on the Armoured Vehicle Launched Bridge (AVLB ) the bridge layer.
The bridge classes are use to calculate the daily tonnage that has traveled across the bridge sections. They are simple added as each vehicle crosses and recorded in the vehicle's drivers log book. The Leopard AVLB can cross 2000t daily over 50,000t for its life. Then at certain tonnage intervals servicing is carried out.
Sorry a bit off track there, Easo
