When canned food was introduced in early 19th century, it became a hit among the rich and privileged who would prefer their food canned. It became a status symbol of sorts and was accessible to poor only through military service. Nowadays canned meat brings to mind dog or cat food, something you'd feed to pets.
Looks like it's running an XL so it could be that it's not a particularly heavy chassis. Looks like only minimal armor and an XL to accommodate 2 head ML's and twin SRM4s. I guess whether it's OP depends on the armor rating of it's skin and how fast it moves. I don't think it has JJ's but I bet it's equipped with ECM to make those SRMs more viable.
