WASHINGTON - The US military commander in Afghanistan, who was tasked to turn around the war in the strife-torn country, is expected to ask the Obama administration for additional troops and equipment, according to media reports Friday, citing a senior US military official. General Stanley McChrystals the request will be for troops and equipment for conducting intelligence, surveillance and reconnaissance, as well as more assets to deal with roadside bombs and explosives, said the reports quoting the unnamed official. The request could be made in coming weeks after McChrystal completes a troop-to-task review to calculate whether there are enough US troops in Afghanistan and the right mix of troops to carry out the militarys war plan at an acceptable level of risk, the official said. The review could also lead to a request for additional troops for either combat or training of Afghan forces, but the official emphasized McChrystal has not made a decision on that. The military already has tasked an additional 4,000 troops to train Afghan forces. The official said McChrystal is likely to submit his recommendations to Defence Secretary Robert Gates as a series of options, with each option having a level of risk attached to it. This will start the discussion within the highest levels of the administration about whether to send a significant number of additional troops, the official said. Gates has signalled he would be open to sending more troops if it could be demonstrated they are needed. But he also has expressed caution that the United States not to send so many troops that it has too heavy a footprint in the country. The troop-to-task review will follow McChrystals assessment of the war, due 60 days after he took command in mid-June. That report is expected to be sent to Gates and NATOs secretary general by August 14, the official said. It will discuss a detailed strategy for success of the counterinsurgency mission, such as the need for US and Afghan forces to conduct more integrated operations and the need to focus on population centres. It is also expected to call for an increase in the number of Afghan security forces. This will be a really frank and honest discussion of how things are, and what it takes to get the job done, the official said.
