Last week, after months of requests, Germany agreed to send German-built tanks called Leopard 2s to Ukraine, to help in their fight against Russia. That decision opened the door for other countries to send their Leopard 2s, including Canada \u2013 which will send four. The US also jumped in, agreeing to send 31 of its M1 Abrams tanks. All in, over 300 tanks are being sent to the country.\n\nNow, Ukraine is asking for more weapons \u2013 including long range guided missiles \u2013 faster.\nBut this begs the question: how will an influx of heavy weaponry change the situation on the ground? Could this mean an end to the war? Or could it mark the start of a new, increasingly violent and dangerous impasse?\n\nRajan Menon is the Director of The Grand Strategy program at The Defence Priorities think tank.
