Storage
It does not stack in structure or vehicle inventories (1 per slot).It can only be stored in the stockpile of Bases (32k max).
Crates of The Ospreay can be directly submitted to any item stockpile that accepts that item to transfer their content.The crates can also be stored in the crate stockpiles of Storage Depots (1000 public, 100 per Reserve Stockpile), Seaports (1000 public, 100 per Reserve Stockpile), Shipping Containers (60), or Storage Ships (1000).
It can be transported by almost any vehicle with inventory slots. However it is much more efficient to transport it in bulk amounts as crates, either delivering them to a Base's stockpile with a Truck or to a crate stockpile with shipping vehicles carrying Shipping Containers.
Tactics
Trivia
- The Ospreay is almost identical in design and function to the American M1 grenade adapter.
- When the Ospreay was released in Update 0.49, it was the direct counterpart to the KLG901-2 Lunaire F, as it could PvP and PvE due to it being able to launch tremolas.
- This was later changed in Update 1.50 ('Inferno'), as the Lunaire also filled the asymmetrical role of the Cutler Launcher 4 (which allowed it to effectively PvE structures). With this change, the Ospreay moved towards a pure PvP role, and removed the ability to launch tremolas.
