I think adding portable mortars and Javelins would be a great idea. Mortars can fire explosive shells from a farther distance, and have some cover to hide behind, so now teams will need to plan out how to disrupt or destroy mortar men. The mortar would deal more damage than RPGs and C4 to vehicles, while dealing less damage than the stinger, so now its accurate to real life mortars. Another weapon I have in mind would be a Javelin or a ground-to-ground missile launcher. This can lock onto all ground vehicles and deal incredible amounts of damage to them, kind of like a stinger but meant for ground. Now, there will be a lock-on range with the Javelin, as it needs to be at a medium range for it to work. The Javelin and Mortar will be really good for distance maps like Iceland, as there is multiple powerful ground vehicles that can be destroyed by them. With the Javelin, you can add that onto the APC, because it has missile slots on there, but they aren't functionable. I believe that the Mortar and Javelin would be a great addition to the game, as it can make players act and think accordingly to disrupt and utilize these weapons to their advantage. Thank you so much for reading my suggestion!
