That is the current RL situation, but it is much better then of WW2 tanks, so it isn't a stretch that future tanks with superior materials and design experience will lead to equipment that can take that level of usage.
The ibex RV is very likely to be wiped out in an instant, if I can afford it I would like to have heavier armor.
The reason you don't put tanks on patrol in rear areas, isn't because of damage to the TANK. Figure this way: 60KPH is respectable (even FAST) for a tracked combat armored vehicle. Civilian cars tend to do 60KPH by the time you're in second gear.
If you're using combat weapons to blow away freeway speeders, your freeways aren't gonna be useful for much of anything. Likewise, tracked vees tend to chew the hell out of roads, pavements, low garden walls, houses, bicycles and people.
This isn't a big deal in combat, but in rear areas and peacetime, those can ramp up some truly awesome and amazing costs to your host nation (and by extension, YOU, since guess who's gotta carry the Liability insurance through MRBC?)
Notable also, dead customers don't pay, and many live ones won't pay if you have a habit of savaging their peacetime infrastructure and accidentally killing their taxpayers.
I'm sure some of the old Cold Warriors who ran riot in West Germany can tell you stories, but those don't even scratch the different legal and contractual elements you'd see as a Merc, given that as a Merc, you're not backed by a soveriegn government.
When the damage deposit starts exceeding your paydays, you are in that famous position of "about to lose a shit ton of money."
even Governments don't do it that way, because the costs are borne directly by them-and governments do not like to lose money through preventable accidents, not even the psychotic dictatorships.
(Dead taxpayers don't pay taxes, dead highway workers don't build roads, dead utilities workers don't fix power lines, get the idea?)
in "Rear areas" anything lightweight, wheeled-or-at-most-hover, with basic infantry weapons and a good radio is what you're going to use for peacetime patrol, because your war-gear is for fighting people with war-gear. Specifically as a Mercenary, where every shot is money out of your bank, and pissing off your client when you don't absolutely have to hits your Rating (and thus, earning power and thus, ability to retain good people and obtain good gear).
Public relations, and public IMAGE matter. If you develop a rep as blundering oafs who crush civilian cars at intersections and wreck towns and farmland, you won't stay in business long-you'll lose good recruits, you'll lose ethical and competent subordinates, you'll lose at the contract negotiating table. You will lose MONEY.
which in turn, means you will lose to the guys who
don't go roaring through downtown in their 60 ton war machines at rush hour, becayse they DO have the Humvee-like Ibex vehicles, and they DO park the 70 ton death machines in motorpools when they aren't preparing for immediate active (read: PAYING) combat.
