Research:

Steel Chariots in the Desert - SC Rolls
Armoured Cars in Eden - Kermit Roosevelt

Pair of WWI armored car memoirs, from Lawrence's driver and TR's son. Both very good, similar books, both spend a little more time on local flora and fauna than on combat against the Turks.

Personal:

Frontsoldaten - Stephen G. Fritz

Not bad, but kind of wish I'd just read Guy Sajer instead, given how much he gets quoted by the author.

The New American Militarism - Andrew Bacevich

Excellent book, found myself agreeing with him a lot more often than not. Should be required reading for all soldiers, civil servants and (especially) politicians.

Flashman at the Charge - George MacDonald Fraser

Maybe the best one in the series so far. Great stuff.
