I hate to seem like I'm stating the obvious, but equipment choice depends on a number of things: mission, opposition, terrain, available personnel, and so on.
For example. My own version of the Atlantis Project doesn't have "Recon Teams". It has "Network Teams" which are tasked with initial contact, survey and assessment (which usually involves interaction with survivor communities). These teams also have a responsibility to 'connect' these communities with the Atlantis Project - and other survivors. Opposition is expected to be very lightly armed. Terrain would be mostly "on-road" and teams would be about 6 people (who have to transport light weaponry and LOTS of communications gear).
Tanks would not be appropriate - but something like an armoured Unimog would be useful.
