Might actually be nice to read what the heck Kaplan and Romney are claiming to talk about. Your text to link.

The key grafs - namely what limitations on force deployment:
(a) 700, for deployed ICBMs, deployed SLBMs, and deployed
heavy bombers;
(b) 1550, for warheads on deployed ICBMs, warheads on
deployed SLBMs, and nuclear warheads counted for deployed
heavy bombers;
(c) 800, for deployed and non-deployed ICBM launchers,
deployed and non-deployed SLBM launchers, and deployed and
non-deployed heavy bombers.

From this, the discussion goes into deployed versus nondeployed and how those count towards the totals.
