However, during the Spring, AA troops were drawn away to the campaigns in Greece and Crete and to the defence of Tobruk, and 2nd AA Bde was left with just five batteries of 9th and 74th HAA Rgts, three independent LAA batteries (one of them Palestinian), and S/L detachments manned by a squadron of the Royal Wiltshire Yeomanry. HQ and two sections of 2 AA Bde Signals merged into Eighth Army Signals, and 3 Section went to Paiforce (Persia and Iraq Force).
