It wouldn't mind the Ohka if it worked something like this:
Your friend picks the G4M2, no formations, in the hangar and selects the Ohka shackles as his load out. He then spawns on the runway and waits.
You pay X perks for the Ohka and select the same spawn point he just did, appearing shackled to the G4M2.
Your friend then carries you to the target. When desired he drops you and you begin your controlled glide in, firing your rocket motor when desired.
All perks are lost. The loss of the perk points symbolizing the loss of the pilot. The perk cost should be significant, in the range of the cost of a single Ar234.
