Now I reckon you guys already know about this, but is it normal that a payload that only cost me 20 oz should do so much destruction?

Now try to finish all those missions properly

Now all we need is a unit of measurement to tell us HOW MUCH IT CAN CARRY.

Any other odd/unconventional tactics and strategies you guys would like to share?

Craft : Drop Crate
Contents : 2 Crabs, each with 3 pineapple grenades, 2 blue bombs, and 1 grenade.
Cost : 90oz
Tactic : Walking Landmines.

Once they pop-out give them go-to commands to spread them around the battlefield. They will sit there idle until an enemy soldier comes across them, at which point the soldier either crushes the crab or shoots it. Upon death the crab will explode and the succession of exploding grenades creates shrapnel that travels with an extreme velocity. If a soldier is very lucky, they will not be hit. Typically the explosion destroys their gun, and takes anywhere from one-third to all of their health.

These are good for slowing down automatically-controlled AI soldiers, as well as harassing enemies which are on guard. Sometimes they are even good to send into your enemy's base.

Most other unconventional tactics end up being reduced to spam, of some variety.
Like flying a rocket horizontally at high speeds, and skuttling it in mid-air so the level is bombarded with debris. But this crab one is a favorite of mine against friends, as it hinders them greatly in being able to send troops at me in groups without having to monitor them along the way.
