I remember the Jaguar - a very square aircraft in cross section (as I think of it) and it was a French/British collaboration.
It (Jag) wasn't really about mixing it in the hand to hand combat thing - it was a trainer and a few other things. I remember the landing gear being really long but not robust.
Also, the French: https://en.m.wikipedia.org/wiki/SEPECAT_Jaguar which was designed to be useable from improvised runways, hence the extremely robust landing gear.
