[Vespers War]

One of the concerns I have with laser weapons is the energy storage needed to support their operation is going to be bulky enough that your anti-drone laser vehicle is likely to be something on the scale of a Stryker that can't carry other weapons or mounted infantry. I expect a lot of countries to focus on advanced autocannon ammunition instead. Either proximity fuses or the timed fuses that are set as the round is being fired based on that round's muzzle velocity and the range to target would be effective against drones when used with 30-40mm rounds. This would give existing IFVs at least some anti-drone capability and let them still function as IFVs, which would give most Western infantry platoons 3-4 anti-drone cannon across their mounts. Each one may not be as effective, but that's mitigated by the increased base of fire plus you avoid the single point of failure issue, spend a lot less on R&D (albeit by spending more on ammo), simplify logistics by having fewer variants, and have anti-drone vehicles that are organic to the unit and can do other things too.
