Does losing a strategic resource make a military unit any less effective, disband them, or else? Or is there no negative effect?

I ask specifically thinking about strategic resources I gain via trade agreements. If I get some oil for example for 90 turns from another civ, and I build planes with that oil, after the 90 turns if the other civ does not renew the trade agreement, do I suffer?

I found this similar question, but it's about buildings instead of units. I could not find anything definitive online that suggested the actual consequences.

In Civ 5, do buildings get any penalties when you lose a source of needed strategic resource?
