Forge Weapon help

I’m trying to have an ordnance drop spawn on my map 2 minutes into the game.
Anyone know how to do this? I want to it to spawn the same weapon every time.
Thanks in advance

EDIT: I got it to spawn but I want 2 to spawn at the same time, but only 1 will.
How do I fix this?

EDIT: I’ve decided not to use ordnance now, so I’m trying to have the weapons spawn just as they are.
Now I can’t get them to spawn. I want them to spawn after 140 seconds. It works on forge, but not on custom games. Vehicles work, just not weapons.

Edit: In the video, Psycho Duck says that Random drops occur every 2 minutes. This is incorrect, the frequency that these spawn weapons is determined by the gametype.
