Agree with Pansarkott.
There is also the case that 'old' equipment was old more in term of expenses and possibly maintenance. For example the Chieftain Mk11 with Stillbrew was still a capable tank, equal or slightly superior to the Challenger I. It made sense to keep them on the line, and possibly replacing the Challenger I with the II. There is also the idea of reforming the 2nd Armored Division. Not that in this specific case I think that much... it is UK... they would find way to blunder and waste money for no gain anyway. Or finding and excuse for cuts...
Other things.... Phantoms still flying in force, as F-111, and A-4 and A-7.
But I am not that convinced that every program will see the light of the day. For example the Stryker. Cool vehicles, and could find their way... but in large part the driving effort behind them was Shinseki and his idea of a post cold war medium weight force plus some vague idea of 'airmobile armor'.
Sgt York... definitely yes. IT was killed not because it was a bad system but because it was slow (M48 hull) compared to an M1/M2 force. On top of that it air superiority was perceived as a given, and thus a SPAAG was seen as a waste. On the other hand, with the 1988 full force structure you can expect several formation still operation on a combination of M113/M60. And the Soviet Frotnal Aviation is not going to the junkyard.
But I will be cautious on a kitchen sink approach. NATO and WP expenditures in 1988 were quite high and I do not see a massive increase of military expenditures. Said that probably big ticket programs (of little relevance for T2k, at least immediately) will grab money due to political dynamics and industry pressure. MX missiles for examples, more B1B bombers, and certainly more moeny sunk on B-2 and V-22, with probably very few airframes available in time..
