I think that it means that some soviet soldier told him, that soviet army stole some F-111 in Vietnam.
I have evidence and material about F-4 Phantom and F-5 Tiger stolen and tested in Soviet union, also some info about iranian F-14, but not about
F-111.
First F-111 prototype flew 21. 12. 1964 and weapon system was accepted in 1967.

Can you provide some more info on the stolen/tested stuff? I'm very interested in this sort of thing.

Just a few information, because it is lot material to translate
Soviets had from Vietnam:
one F-5E with two additional engines and technical documentation
-tested mainly by A. S. Bezevec
-when moved to Soviet Union by ship, vietnam soldiers welded {!!!!} wintips, because they were to large. Hardly, but it was repaired.
-flown dogfights against MiG-21SM and MiG-23M
one A-37B with equipment and technical documentation
-tested by O. N. Muchin
-some experience used in improvements and development of Su-25
one CH-47
-compared to Mi-17
one UH-1
-compared to Mi-17
It was planned also to move one AC-119, but it was too big, so only weapons were removed and tested.
All planes were tested from 1976 at Tschkalovskaya test site near Moscow and flown at Aktubinsk polygon in Astrachanya. Tests were headed by V. M.
Tsumbarov and ended at early 1977. A-37B was moved to OKB Sukhoi.
