Swedish pbv 401 or 407/Russian MTLB

[Antenna]

Somewhere in the 90's Swedish Goverment bought around 700 MTLB/MTLBu's from united Germany (former East German stock of armor).

Couple of years ago I was involved with half of a leg in a study where the aim was to upgrade the pbv 401 to something with more teeths.
Enter the pbv 407 concept.

The study pointed out for instance
- change of the engine (more fuel efficient diesel)
- new gearbox
- broader tracks (better performance in marches and snow)
- similar turret as the AAVP7 (Mk-19/M2Hb-combo one man turret)
and some more changes that I don't remember any longer.

Swedish armed forces has for many decades upgraded their old stuff to fit a new game of warfare (centurion tank, AJS 37 "Viggen" etc...)
So what do you think guys, is this the future also for say old M113/M113A1 etc... to be upgraded thru the war or say weeks or months before the T2k war begins.
