Unfortunately you are using the SP carry categories, which really do not properly reflect the real life carry capacities of units. (With regard to guns, vehicles etc anyway).

The chinook has a carry capacity of 244, to allow a decent number of leg troops to be carried, and also a small vehicle (hence the 2XX code). But a 210 carry capacity would limit the thing to just 10 grunts (or 1 hummer). 4 hummers would be a reasonable load for a landing craft with about 250 load code though.

Carry capacity in SP has nothing to do with "tonnage" - it is just a "magic number".

M113 and sheridan are really too heavy to actually be carried by chinook - you should limit yourself to a jeep/hummer and when doing so, no extra passengers. Chinooks rarely actually carry vehicles, just grunts.

Otherwise you are simply using/bending the game system mechanics to allow yourself unrealistic outcomes compared to real life.
