Sparse logistics soldiers facing the sentence

The last sentence is tight infantry and loose artillery.

Close infantry, loose artillery, sparse logistics.

Infantry management is relatively strict, and it is all kinds of training. Artillery management is relatively loose, mostly professional and technical. No one is in charge of the logistics of the soldiers. They are all just fine because of their work, and their discipline style is relatively lax.

The whole sentence should be: the infantry is tight, the artillery is loose, and the government soldiers are scarce, fooling around as logistics soldiers.
