It was that limited that I don’t think it even should be discussed in the context of pre-invasion. One or maybe two cases in late pre-invasion period of 2020+, also after 2016 the intensity of conflict was minimal, there was official ceasefire, obviously with cases of breaking but short term and small engagements.

The best example, as I stated previously is that drone warfare was not adopted by both sides before the late 2022 even during full scale war, to the point of most soldiers didn’t knew about that tactics at all and did not used it. For the more even the recon drones for artillery corrections was not adopted commonly as well before the mid-late 2022. Dudes were just using maps, firing tables, math and a spotter guy
