In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Q: What instrument used in military troop deployment has revealed unsavory activities in its procurement?, Context: Kenya's armed forces, like many government institutions in the country, have been tainted by corruption allegations. Because the operations of the armed forces have been traditionally cloaked by the ubiquitous blanket of "state security", the corruption has been less in public view, and thus less subject to public scrutiny and notoriety. This has changed recently. In what are by Kenyan standards unprecedented revelations, in 2010, credible claims of corruption were made with regard to recruitment and procurement of Armoured Personnel Carriers. Further, the wisdom and prudence of certain decisions of procurement have been publicly questioned.
A:
Armoured Personnel Carriers
