The problem with modern tanks in this context is theyre less big guns on tracks and more massive computers on tracks which happen to have big guns. A leo can smack targets on the move kilometres out, long before the enemy could even see them...but that means the FCS and associated electronics are super precise and complex. Other countries have reservists with tanks so its doable, it will just require the very large logistical footprint that all tank squadrons require. I personally think that is worthwhile from a persgen standpoint as a crewman but recognize that competing priorities probably come first. Better to have lighter, simpler autocannon-armed AFVs that can be deployed with CARBs and at least provide gunnery and tactical foundations for future MCAV augmentation.
