Adding Modern Artillery Vehicles (M142 HIMARS, MLRS) to Battlefield 6

Superficially this is an alright idea, but I feel like it is quite naive and ignorant of the realities of online play. Here's why:

• Artillery players would simply grab the HIMARS or equivalent artillery system and stay in their main base to, in effect, camp with impunity.
• Artillery as described by you and in the comments here would essentially be a doomsday weapon, with people insisting on massive explosions and extreme effect on target which, while realistic, doesn't make for very interesting gameplay on the receiving end.

Furthermore, I do not personally feel that the launch maps are large enough to lend itself well to the inclusion of highly capable artillery systems, like the HIMARS or its equivalents.

As for your "Why this matters" list, I'll present some counter-arguments:

1. Realism & Modern Warfare Representation - In current warfare, such as in Ukraine, artillery has a major role in the conduct of operations. However, these assets are pretty much never located even in proximity to the FLOT/FLET as would have to be the case in Battlefield. I would argue that seeing a HIMARS system would make the battlefield far less authentic and less relevant to today's use of artillery systems.
2. Strategic Depth - You're pretty spot on in this point, though as you mention "long-range strikes", I will refer back to my point about artillery players camping in main base with impunity.
3. Balanced Gameplay - This seems to disregard the implementation of ammunition resupply point being present in main base, thereby making the point about limited ammunition null and void. Long reload times, yes, could be an option. The need for spotters/drones for targeting is rendered inconsequential given the size of the maps relative to the range of the artillery system.
4. Unique Player Roles - Artillery would provide a new avenue for support players to contribute to the battlefield, but my concern, once again, is that they would do so from their main base with impunity.
5. Immersion & Variety - Introducing on-map artillery vehicles would not do much at all to make the match feel different and more unpredictable. Artillery would simply be another point of friction and annoyance to the recipient that can not retaliate against the sender.

I personally am not principally opposed to having artillery as an aspect of Battlefield games, but I am principally opposed to having them as on-map assets due to the extreme disregard of how these types of assets actually work.

I'd much rather see something like the BFV squad call-in system but for a Small Diameter Bomb (GBU-39 SDB) strike that could be intercepted by anti-air systems.
