I remembered description from contingency scavs and meanwhile noticed, that even pre-cont scavs could have some more interesting techs/units.
- Baba sniper (of course if infantry were not excluded): two kinds of antimaterial sniper rifle, low cal (12,7 mm), med cal (14mm or 16mm) and hi-cal (20mm). Low cal one - with AP type (for infantry, wheels and hover, just like today) and high rate. Hi-cal is cannon-type, so should be affected by all cannon upgrades. For some fun, low-cal could be salvo weapon, with good ROF in salvo, and some delay for recharge (still faster than for mini rockets).
- Other baba types:
flamer
grenadier (40mm GL)
bomber - close-range gui, delivering anti-bunker/anti-structure charge.
rocketman (counterpart for rocket cyborg, but with minirocket cal),
reconciler and/or target-designater aka sensorman ))
may be some sort of ataman aka comander

, essentially acting as designater
worker and engineer. There could be repair vehicles, with common elements from evacuators.
or may be really
- jeep adaptation of heavy AT missiles (inspired by TOW launcher).
Given what is highest tech for uscavs (nexus tank), thay also could have some T2 spec techs:
- multibarell MG for copters, vehicles (

- pepperpot based: 6 shots salvo baba GL (unsure if baba at 2100 could have chaingun GL, kkk), same for vehicles, including copters. Regular mortar is probably only for ground vehicles.
- ripple rockets based: heavy missile launcher with similar range (requiring sensor for best use), seems essential continuation from minirockets. May be lower (1 to 4) rocket number in salvo.
Btw, remembered minigun bi-cycle from the "Machete" trash movie X)
T3 based:
- long-range homing AA missiles aka stinger (though imho, homing should be available just by laser designator).
- finally enabling homing for AT
- laser, gauss and rail guns for vehicles
- hacker

(uscavs already have nexus tank)
- emp based: electro-shocker baba, vehicle microwave anti-crowd emitter.
Btw, it looks funny, how babas are "brainwashed" by nexus weapon.
Those, who sacrifice culture for bit of freedom don't diserve any.
