If you are using a Leopard, upgrade ASAP. You are only carrying a lance of Mechs, and either 2 ASF, an ASF and a platoon, or 2 platoons, or maybe a few vehicles.
One of the better Dropships to use, as long as you don't put it into hostile environments is a Mule. Lots of cargo capacity that can have Mech and Vehicle bays added in (though you will need to cut the hull if you want to drop the Mechs), so you can carry a very nice size force, and even trade with the locals. You might get a contract to guard an LRM factory, and while there you might as well try to buy the LRMs at factory pricing instead of sale price.
That could be a fun 'partnership' mission. You get a contract to raid an LRM factory and steal its output with the hiring organization gets half. But before you perform the raid, you send a fast small craft with a negotiator down to the factory to purchase the factory-built LRMs, and arrange that only a couple tons of LRM ammo are left over. So you 'loot' the factory for 2 tons of LRM ammo, give 1 to the person who hired you, and put the other 998 tons into your ship's cargo hold.
"Sorry, they had just sold a large chunk of the output before our raid. This is all they had left."
You can also perform a lightning raid, and after the raid is over, talk to the locals about selling the extra equipment on your Dropship to help rebuild their forces.
"Sorry about that, our contract said we had to do a raid here. But we do have 30 light and heavy vehicles in our cargo bay that are for sale for the next hour, if we can come to some sort of an agreement. A nice mix of Demolishers, heavy LRM carriers, and scout VTOLs. Shall we talk price?"
