A is for........Army truck

I have decided to challenge myself to come up with some blips that are different from my usual and to make it even more of a challenge, work my way through the alphabet as well. I stumbled at the first hurdle today as I found 'A' really difficult and tried really hard to resist 'A is for.....Apple'. I had a few different ideas but couldn't quite get my head round any of them and this is actually my second choice but I have to blip something for continuity.
This truck is just parked outside someone's house in the village and I have no idea what it is used for, I spotted it when I changed my normal walk route because of the floods. I had to wait until the afternoon for the sun to poke through the clouds :-)
